Trending Drier This Week

| 3:26 pm May 18, 2015

RADAR UPDATE: Showers and storms are most numerous over the northeast counties of Alabama this afternoon… but more could form over the next few hours in the moist environment.

TOMORROW: A surface front will push through the state, but there is little upper support, and with warm air aloft we really don’t expect much more than widely scattered, mostly afternoon showers or storms. Otherwise, expect a mix of sun and clouds tomorrow with a high in the mid 80s.

REST OF THE WEEK: I still don’t see much reason to forecast any chance of significant rain Wednesday through Friday. These three days look warm and mostly dry, with partly to mostly sunny days and fair nights. Afternoon highs will remain in the mid 80s, just a few degrees above average for mid to late May in Alabama.

MEMORIAL DAY WEEKEND: No real change for Saturday; partly sunny and very warm with a high in the upper 80s. Then, on Sunday and Monday, we will introduce the risk of “scattered, mostly afternoon and evening showers and thunderstorms”, which is almost a daily part of summer weather in Alabama. The high Sunday and Monday will be in the mid 80s with a mix of sun and clouds both days.

GULF COAST WEATHER: About 8 to 10 hours each day through the holiday weekend along the coast from Panama City west to Gulf Shores; just a few widely scattered showers and storms each day. Highs on the immediate coast will be in the low 80s, with mid to upper 80s inland. The sea water temperature at the Dauphin Island Sea Lab is 83 degrees this afternoon.

Moist Air Still Hangs Over Alabama

| 6:31 am May 18, 2015

RADAR CHECK: Showers and storms are confined to the northwest corner of Alabama at daybreak…

Screen Shot 2015-05-18 at 6.17.40 AM

We should also note there is a dense fog advisory for parts of Central and South Alabama, where visibilities are very restricted. That fog burns off by mid-morning.

We will project scattered to numerous showers and storms across the state later today and early tonight, but no severe weather issues with the main dynamic forcing passing well to the north of our state. Best chance of showers and storms will come from about 2:00 p.m. until 8:00 p.m…. and the high should be in the low to mid 80s with a few intervals of sunshine possible, much like yesterday.

TOMORROW: A surface boundary will pass through, but with little upper support, and a rather stable airmass, we don’t expect much more than widely scattered showers or storms. Otherwise, expect a mix of sun and clouds tomorrow with a high in the mid 80s.

REST OF THE WEEK: The weather looks mostly dry and warm Wednesday through Friday with highs holding generally in the mid 80s. We do note the European model (ECMWF) pushes unstable air back in here Thursday, suggesting some risk of a few scattered storms, but we will discount that for now.

MEMORIAL DAY WEEKEND: Saturday looks warm and dry with a high in the upper 80s, but we will introduce the chance of scattered showers and storms Sunday and Monday. No wash-out, and the sun will be out at times, just be ready for a passing shower or storm from time to time on these two days, much like the weather yesterday.

GULF COAST WEATHER: Looks good through the holiday weekend. About 8 to 10 hours of sunshine each day from Panama City west to Gulf Shores; each day there is a risk of widely scattered showers and storms, but nothing out of the ordinary for late May. Highs on the immediate coast will be in the low 80s, with mid to upper 80s inland. The sea water temperature early this morning at the Dauphin Island Sea Lab is 79 degrees.

So That Is Why I Am Sweating…

| 1:33 pm May 17, 2015

There has been a stubborn mini-ridge of high pressure holding sway over Alabama and the Southeast for the past several days. Visible satellite imagery showed the two rivers of air moving across Alabama this morning clearly: a south southeasterly low level flow around the surface high and a southwesterly flow aloft ahead of the western trough and up and over the southeastern ridge. Clouds were thickest along and east of I-65 this morning, with sunshine over western sections pushing the mercury into the 80s in places like Tuscaloosa, Jasper, Hamilton and Muscle Shoals before noon.

Cumulus clouds were starting to develop at the convective temperature (81F) was reached. Isn’t the atmosphere amazing in its predictability (at least on some levels!)

2015-05-17_12-24-31

GEEKING OUT: The precipitable water value this morning based on the sounding from the National Weather Service office at the Shelby County Airport was 1.76 inches. This is right at the highest ever measured (1.77″) across Central Alabama, with records going back to 1964 at Gunter AFB in Montgomery, along with soundings from Montgomery and Centreville.

2015-05-17_13-30-50

WILL IT RAIN? About 50% of you will have a little ran fall into your lives this afternoon as scattered showers and storms develop with the strong heating. Showers and storms have formed over northeastern Mississippi and Northwestern Alabama. Other newly formed showers were in East Alabama over Randolph County. Additional showers and storms will form through the afternoon and evening before dissipating around midnight. Highs this afternoon will range generally between 83F and 86F. Lows tonight will be in the middle 60s.

FOR YOUR MONDAY: Central Alabama will remain in a moist regime tomorrow as well with the approaching cold front still well to the northwest. More showers and storms will likely form to the west and push into the state at some point during the day. Highs will be well into the middle and upper 80s with a about 5-7 hours or sunshine in between and around the showers and storms.

TUESDAY: The cold front will push into Alabama on Tuesday morning and travel southeastward across the state. Some drier air will filter in behind the front, even as it fizzles over South Alabama through midweek.

Passing Showers Remain Likely

| 6:36 am May 17, 2015

Central Alabama and the Southeast US remains in a moisture rich air mass as we see no big changes to the overall weather pattern today or into the week ahead. A quick check of radar this morning showed some light scattered showers across the state producing generally light rainfall amounts. Thunderstorms were fairly numerous along the Gulf Coast yesterday including a couple of flash flood warnings in the Mobile area.

BMX

Passing showers will also be the going weather for the beach area today with only a few peeks at the sun. Activities at The Hangout in Gulf Shores will remain in full swing with the possibility of some delays due to showers. The onshore flow is also creating a high risk for rip currents, so if you plan to be at the beach, be especially cautious if venturing into the water. The threat of a passing shower reduces into early next week, but there will still be a good amount of clouds with highs in the middle 80s with the daily threat of a scattered shower or thunderstorm.

The closed upper low over the Southwest US ejected northeastward yesterday and was the focus for a round of severe weather in the Central Plains states. That closed low will be opening up and moving north to northeast today and will be the focus for a severe weather into the Great Lakes area trailing back into the Mid Mississippi River Valley.

The upper ridge will be holding in place as the upper closed low opens up and moves into the Great Lakes. While this will help to dampen the upper ridge somewhat, the overall meandering of the upper ridge should keep our heights fairly stable so not much change in temperatures with highs in the 80s and lows in the 60s. And with a slight west to southwest flow aloft, clouds will be remaining with us. Passing showers will mean that not everyone gets rain, however, with the heavier showers some spots could see some locally heavy rain with amounts of one half to one inch possible.

With the upper ridge dampened somewhat at midweek, we should see a brief break in the chances for showers. The chance of rain will not drop to zero, but it does look like Wednesday should be a dry day for most of us. The upper ridge remains along and just west of the Mississippi River for the latter part of the week, so the forecast will have to show small daily chances for showers driven primarily by the heat of the day. It won’t be especially hot, however, with highs holding in the 80s and lows in the 60s for Central Alabama.

As we edge out into voodoo country, not much change in the overall upper air pattern, so the summer-like pattern with showers appears likely to stick with us into the latter part of May.

Watch for additional posts here for updates on the anticipated weather. James Spann will have the next edition of the Weather Xtreme Video here on Monday morning. Enjoy your day and Godspeed.

Muggy May Weather

| 3:10 pm May 16, 2015

The southerly flow over the state continues to bring ample moisture into the state. Uncomfortable and humid conditions continue today as dew points are into the 60s and 70s. Plenty of moisture is in place and we are seeing plenty of showers on the radar this afternoon. The sky is mostly cloudy and with numerous showers and storms across the state. Temperature this afternoon are near 80 degrees for much of Central Alabama.

5-16-2015 3-02-54 PM

RADAR CHECK: Much like yesterday, we are seeing a cluster of showers and storms lifting north across the state and many locations will see rain the next several hours. The main activity continues to be across South Alabama, but it is moving north and will be impacting Central Alabama later this evening. Throughout Central Alabama we are seeing showers develop and we should continue to see these increase in  coverage the rest of the afternoon. Showers and storms should begin to wind down slowly once the sun sets and daytime heating is loss.

5-16-2015 3-04-40 PM

What you see today is what you get tomorrow. Expect a near repeat performance in the weather tomorrow as a moisture-rich atmosphere will allow for passing scattered showers and storms at just about anytime, but with a great coverage during the afternoon and evening. Highs tomorrow will be in the lower 80s for most of Central Alabama.

Passing Showers Through Weekend

| 6:53 am May 16, 2015

Quick radar check shows an area of showers in the Tennessee River Valley moving northward. Other scattered showers were occurring in the vicinity of Selma. Our moist air mass will lend itself to passing showers through the weekend, however, with the clouds in place our highs will be held into the lower half of the 80s.

BMX

Passing showers will also be the going weather for the beach area today with only a few peeks at the sun. The onshore flow is also creating a high risk for rip currents, so if you plan to be at the beach, be especially cautious if venturing into the water. The threat of a passing shower reduces on Sunday and into early next week, but there will still be a good amount of clouds with highs in the middle 80s with the daily threat of a scattered shower or thunderstorm.

The upper air pattern remained somewhat stagnate for the time being with a closed low over the western US. That closed low will be opening up and moving north to northeast today and will be the focus for a significant round of severe weather in the Central Plains where SPC has a moderate risk of severe weather in portions of Oklahoma, Kansas, and South Central Nebraska. The risk of severe storms diminishes to the standard slight risk on Sunday as the upper low moves into the Great Lakes.

For us, the upper ridge will be holding in place as the upper closed low opens up and moves into the Great Lakes. While this will help to dampen the upper ridge somewhat, the overall meandering of the upper ridge should keep our heights fairly stable so no real change in temperatures with highs in the 80s. And with a slight west to southwest flow aloft, clouds will be remaining with us until midweek. Passing showers will mean that not everyone gets rain, however, with the heavier showers some spots could see some locally heavy rain with amounts of one inch or slightly more possible.

With the upper ridge dampened somewhat at midweek, we should see a brief break in the chances for showers. Not sure the chance of rain will drop to zero, but it does look like Wednesday should be a dry day for most of us. The upper ridge remains along and just west of the Mississippi River for the latter part of the week, so the forecast will have to show some small daily chances for showers driven primarily by the heat of the day. It won’t be especially hot, however, with highs holding in the 80s and lows in the 60s for Central Alabama. These values should be pretty close to our 30-year averages of 81 for highs and 60 for lows.

As we edge out into voodoo country, not much change in the overall upper air pattern, so the summer-like pattern with showers appears likely to stick with us into the latter part of May.

I expect to post the next Weather Xtreme Video here on Sunday morning. You can always check back here for later updates on Central Alabama weather.

A Long Way From Home

| 6:32 pm May 15, 2015

UPDATE JUST AFTER 7
Power is reported out in the Brook Highland shopping area and in Bessemer on 9th avenue between 16th and 19th street. But don’t worry, the storms are not severe. At 7:10, they are lined up from west to east from Gorgas to downtown Birmingham to Pell City.

2015-05-15_18-27-22

A line of heavy showers with some lightning is pushing into the southern part of the Birmingham Metro at this hour.

They will bring brief heavy rain, gusty winds and some lightning as they move across parts of Pickens, Tuscaloosa, Jefferson, Shelby and Talladega Counties over the next hour.

The storms have weakened over the past couple hours as they have moved north from the Gulf Coast. They apparently started out this morning as the seabreeze front, from that refreshing flow off air off the Gulf that forms as the land heats during the day. It is a long way from home tonight, not an unusual occurrence in Alabama.

Scattered Shower/Storms Over The Weekend

| 3:45 pm May 15, 2015

RADAR CHECK: Showers and storms have been scattered across Alabama today; this afternoon the more numerous ones are over the southern counties… moving northeast…

Screen Shot 2015-05-15 at 3.34.14 PM

THE WEEKEND: Not much change; a moist airmass will linger over Alabama tomorrow and Sunday. The sky will feature more clouds than sun, and on both days we will deal with scattered showers and storms. Like today, their location and timing will be pretty random, meaning we can’t give specific start/stop times for rain. If you will be at an outdoors event, just be ready for a passing shower or thunderstorm; the more numerous ones will come during the afternoon and evening hours, but we can’t rule out a late night or morning shower.

No “wash-out”, no severe weather threat, and the sun will peek out at times, much like today. Afternoon highs will be in the low to mid 80s. They will get the golf rounds in at the Regions Tradition at Shoal Creek, but a delay or two is possible if thunder is near the course.

We should mention tomorrow could bring a pretty significant severe weather setup to parts of the Great Plains…

day2otlk_1730

NEXT WEEK: Showers and storms remain possible Monday, but drier air moves into the state Tuesday. We expect a good supply of sunshine Wednesday and Thursday… then some risk of showers will return late in the week on Friday. Highs will be mostly in the 80s; see the Weather Xtreme video for maps, graphics, and more details.
