Don’t forget to set you clocks ahead one hour before heading to bed tonight. Daylight Saving Time begins at 2AM Sunday Morning, which means that we will spring forward to 3AM. This will give us less daylight in the mornings and more daylight in the evening times and more of an opportunity to enjoy the warmer temperatures that are now beginning to settle in across the state. You don’t want to miss any of this spring-like weather this weekend, make sure your clocks are set correctly. Days will continue to get longer until the Summer Solstice on June 21.
If you are out and about today, you have noticed how great the weather is across Central Alabama. Mostly sunny, dry, temperatures approaching 70 and a light winds. A beautiful early spring day is what we are all seeing today and this will hold true tomorrow as well. Dry weather will last for the rest of today and should last through tomorrow before our next storm system moves in late Sunday night, which means we will probably wake up to the showers and thunderstorms for Monday.
Temperatures across the country are really not that bad. Warms air is in place across much of the east, even places in New England that saw over a foot of snow a couple of days ago are seeing temperatures into the 50s this afternoon. 70s are stretching as far north as Missouri and Kansas. Areas across the Midwest and Northern Plains are in the 20s and 30s, which is not to bad for this time of year. No brutally cold weather in the continental U.S.
A quick look at the national radar shows a line of thunderstorms along the Interstate 35 corridor. Some storms are severe and there is a severe thunderstorm watch that does include the Dallas/Ft. Worth Metroplex. That line of storms will continue to move east overnight and should be impacting the Lower Mississippi River Valley tomorrow. These storms will loose some of their punch and organized severe weather is not expected in the region tomorrow. The precip in the Central Plains and Midwest is snow. Blizzard warnings are in place across the west central Plains and sections of South Dakota and Minnesota could see up to to half a foot of snow.
Depending where you are in state, you are either seeing clouds or sun. Luckily we are all warm this afternoon, but locations with the sun, it does feels much warmer. This really is a great weekend for weather, as we are seeing a sneak peek of the spring-like weather that will be heading our way more often in the near future.
Clouds hanging tough along the Interstate 20 corridor, but the sun is shining in areas around Jasper, Fayette and Hamilton. Also location in our southern counties are seeing more sun as well. Hopefully the clouds in the Birmingham metro, Gadsden, Anniston and Tuscaloosa will get out of here during the next couple of hours and make it a sunny and very warm Saturday afternoon.

Central Alabama is in for a spring-like weekend as temperatures warm up nicely with a gradual return to a southerly flow. The air near the ground remains quite dry, so despite the appearance of some patchy echoes on weather radar, I do not expect anyone to see more than a few spits of rain with the passing clouds. Highs should warm nicely today into the upper 60s with lower 70s for Sunday.
Sunday night into Monday the upper trough now over the Southwest US will eject eastward bringing a strong low pressure storm system through the Central Plains and dragging a cold front into the Southeast US. The front will move slowly across Alabama on Monday. Rain should stay to our west on Sunday as clouds increase with rain entering the state after midnight. The front will move through slowly so that rain is likely to occur for much of the day Monday. The front exits the state early Tuesday morning which brings drier weather to us Tuesday. We should see sun by late Tuesday morning and Tuesday afternoon. But as the upper trough passes we return to a northwesterly flow aloft bringing another cool down to us. This one should drop our highs back into the upper 50s for highs on Tuesday.
Severe weather is not expected to be an issue with the passage of the upper trough and the cold front. Instability values do climb much so there is no specific risk area identified by SPC for Day 3, Monday. Rainfall amounts on Monday should be in the 1 to 2 inch range thanks in part to the slow passage of the front.
It is good to note that the GFS and the ECMWF are in very good agreement on the passage of the front on Monday, both in timing and position. This agreement in the two models enhances confidence in the forecast.
The northwesterly flow aloft does stick with us into the latter half of the week but slowly loses its grip on us as the big ridge to our west slowly moves our way. The result for us will be a gradual warming trend with highs slowly climbing toward the 70-degree mark by next Friday. Lows will warm slowly, too, starting out in the mid and upper 30s on Tuesday and Wednesday and climbing into the 40s by Friday.
James noted yesterday that we might be in for a long dry spell according to the GFS run yesterday morning. Looks like that has changed. The 06Z GFS run today shows a substantial ridge for us for week 2, however, the southwesterly flow should bring a good deal of Pacific moisture in our direction which means that week 2 could be warm AND wet. Time will tell.

I was at Academy Sports in Tuscaloosa on Thursday, and what a turnout we had for programming weather radios. It was great to see the large crowd, and it was a great feeling to help get so many people prepared for severe weather this spring. I hope you have a great day whatever your plans. I expect to have the next Xtreme video posted first thing Sunday morning. And don’t forget to set your clocks again tonight when you go to bed! Godspeed.
