Brian Peters: Stormy weather for Alabama later today

Brian Peters: Wet week ahead for Alabama, with storms to watch tonight from Alabama NewsCenter on Vimeo.

TODAY: The sky was mostly cloudy for the northern two-thirds of Alabama this morning, with most of the state in the 60s. Keep in mind our 30-year average low for late February is 39 degrees. There were a few showers on radar this morning across the western sections of the state, but the main show will come tonight as an upper trough swings by and a surface front moves into Central Alabama.

The Storm Prediction Center has a small chunk of the northwestern corner of Alabama in an enhanced area, while the slight risk for severe storms covers about the northwestern quadrant of the state.

Storms are expected to develop later today in the Ark-La-Tex area and move eastward as the strong short wave over the Four Corners area accelerates rapidly northeastward, with a strong surface low developing in the vicinity of northeast Oklahoma. The upper ridge will help to keep much of the dynamics to our north as the overall system weakens coming into Alabama. Still, there is definitely a risk for severe weather tonight into early Sunday morning, so be sure to have a way to receive weather warnings, especially while sleeping.

NEXT WEEK: The front pushes into the Southeast but stalls out across Central Alabama Sunday evening as it comes parallel to the upper flow. A second short-wave trough will move across the Mississippi River on Monday, bringing an end to the rain. Highs Sunday and Monday will drop back into the 60s from the unusual warmth we’ve seen.

Tuesday should be dry for Central Alabama, but another short wave digs into the Four Corners area on Tuesday and rapidly ejects northeastward on Wednesday. This brings the front back north as a warm front and introduces another chance for severe storms Wednesday into early Thursday, with a surface low developing in Oklahoma and rapidly intensifying and moving to the vicinity of Chicago on Thursday morning, hence another potential for severe storms in the Lower Mississippi River Valley.

The rain moves out on Thursday as an upper ridge develops and moves across the central United States. Friday and Saturday should be dry, with high temperatures around 60.

MORE COLD AHEAD?: Look for some big changes once we head into voodoo country. The Global Forecast System is developing a deep trough once again along the East Coast. This pattern is strangely suggestive of more chilly weather for the eastern half of the country, so I hope the coats have not been stored away just yet.
