We’re Losing The Sun & Storms Are Losing Their Strength

| September 18, 2016 @ 7:14 pm

radar

Storms have really lost their strength since the last post as the sun has made its way beneath the horizon. There are still a few showers in progress over in eastern parts of Central Alabama at this time, as they are continuing to push off to the east towards Georgia. None are of any concern and should start to fall apart in about an hour.

As for the storms that were pushing in from Mississippi earlier, almost all of those have dissipated within the last hour. There is a decent storm that is pushing to the south in southern Sumter County that is putting down some heavy rain and is still showing some lightning strikes.

Looking at the latest run of the HRRR, these showers will continue to diminish over the next few hours and we should have no concern for any of these becoming strong.

More Storms Now Pushing Into Northwestern Alabama

| September 18, 2016 @ 5:06 pm

radar

At the 5PM hour, we have storms starting to push their way in from Mississippi, as they are now entering into the northwestern corner of the state. They are moving to the east at about 20-25 MPH.

A stronger storm that has developed ahead of the line of storms has warranted a Significant Weather Advisory for Northern Greene and Northwestern Hale counties until 5:30 PM. A strong thunderstorm was located near Mantua and just southeast of Aliceville, and was moving to the southeast at 25 MPH. Winds in excess of 40 MPH and dangerous cloud-to-ground lightning can be expected. People in Eutaw, Moundville, Akron, Union, Wedgeworth, Evansville, Mantua, Knoxville Walden Quarters, and Sawyerville are in the path of this storm, so take shelter until it passes.

Otherwise across the state, just scattered showers and a few thunderstorms are out there mostly are east of I-65. There are no watches and warnings in effect, and should be that way throughout the remainder of the daylight hours. We’ll take what ever rain we can get.

Midday Nowcast: Hot & Humid With Some Strong Storms Out There

| August 26, 2016 @ 1:42 pm

Radar

At this hour, scattered showers and thunderstorms are active across the northern half of Central Alabama, with a few of these prompting Significant Weather Advisories on them from the NWS. One has been issued for a storm located near Detroit in Northwestern Marion County, with the main threats being from winds in excess of 40 MPH, frequent cloud-to-ground lightning, and torrential rainfall which could lead to localized flooding. Advisory expires at 2PM. Another advisory has been issued for a cell near Bluff and Winfield in Northwestern Fayette County until 2:15PM with the same threats. All of the rain is moving slowly to the east-northeast.

TEMPERATURES AT THIS HOUR: Here is a list of temperature observations from across the area at this hour:

Birmingham 91
Tuscaloosa 93
Gadsden 91
Anniston 91
Cullman 89
Jasper 95
Alexander City 94
Selma 91
Montgomery 92

CODE YELLOW AIR QUALITY: The Air Quality Index for the Birmingham Metropolitan Area is in the “Code Yellow” for ozone and particulate matter 2.5. Unusually sensitive people should consider limiting prolonged outdoor exertion.

TODAY’S CLIMATOLOGY FOR BIRMINGHAM: The normal high for August 26th is 89, while the normal low is 68. The record high for today was set back in 1943 at 103. The record low was set back in 1966 at 55.

REMAINDER OF TODAY: Another hot and humid day expected for Central Alabama this afternoon, with a small risk for widely scattered showers and thunderstorms. Latest HRRR is showing the better rain chances north of the I-20 corridor. Afternoon highs will be in the low to mid 90s. The odds of any one spot getting rain today will be around one in four.

WEEKEND WEATHER: Much of the same news for the weekend, as it looks like the typical summertime weather pattern will be in place for a while. It will be hot and humid, with partly clear skies, and a small risk for widely scattered afternoon showers and thunderstorms. Afternoon highs will mostly be in the low to mid 90s. The odds of any one spot getting rain will be around one in four.

HEADED TO THE BEACH: The weather looks great on the coast from Gulf Shores to Panama City Beach through the weekend, with mostly sunny days, fair nights, and only widely scattered showers or storms. Highs will be in the upper 80s on the immediate coast, with low to mid 90s inland. The weather next week will depend on what happens with 99L, and if there is any impact (and that remains a big “IF”), it should be over by the Labor Day weekend. See a very detailed Gulf Coast forecast here.

TROPICAL STORM GASTON: This storm is beginning its turn back out to open water, as it is headed to the north-northwest at 17 MPH. Maximum sustained winds at this time are at 65 MPH. Gaston is still expected to become a hurricane again at some point today, but will be no threat to land and recurve well east of Bermuda and back out into the open water.

Screen Shot 2016-08-26 at 6.18.39 AM

INVEST 99L: Strong winds aloft are continuing to wreak havoc on this wave as shear is keeping any development from happening. Model data is not especially helpful right now since there is no way the system can be initialized with no low level center or structure. Each batch of runs will continue to do the hokey pokey.

Concerning global models, the Euro (ECMWF) brings a very weak system across the Florida Peninsula, and then out into the Atlantic well east of Alabama. The GFS brings a weak system up toward the Central Gulf Coast toward the middle of next week, and the Canadian (GEM) brings a slightly stronger system toward Panama City Beach early next week. All three can’t be trusted for the same reason mentioned above at this time. There is a very real chance that 99L never develops into a depression or storm. And, if it does, few models show much beyond a weak tropical storm. Rain would be the main issue is land is impacted. All we can do at this time is just keep watching to see if anything can survive the sheared environment it is in now.

ON THIS DAY IN 1989: Anchorage, AK, was soaked with a steady rain, and the 24 hour total of 4.12 inches smashed their previous 24 hour precipitation total of 2.10 inches. It also pushed their rainfall total for the month past their previous record for August.

Strong Storms Pushing Through Central Alabama

| July 14, 2016 @ 9:19 pm

radar

A line of pretty intense thunderstorms are pushing through Central Alabama at this time. The line stretches from the AL/TN state line in Madison and Jackson counties, back to the south-southwest down into Bibb and Perry counties, and back to the west in Meridian, Mississippi.

The strongest part of the line is located in the southwestern parts of Jefferson County where some rainfall estimates are up to 1.8 inches within the last hour. Lightning is starting to ease a little, but still some area of intense strikes. Most of the rainfall has fallen in the northern Jefferson County areas, where there are several radar rainfall estimates of 1.8 inches, especially just west of Warrior and Kimberly.

Strong gusty winds up to 40 MPH can be expected with these storms, along with some small hail, heavy rainfall, and copious amounts of cloud-to-ground lightning.

This will probably be the last round of storms for the night, as another line has entered the western parts of Mississippi, and will probably enter the state sometime between Midnight and 2AM. These storms have several severe thunderstorm warnings on them, and a severe thunderstorm watch is in effect until 1AM for much of Central Mississippi.
