FIRST ALERT WEATHER: Big changes this week

Happy Tuesday! A northwest wind will blow today, and there will still be some significant cloud cover through this morning. It will thin some this afternoon, but this will be the coolest day of the week. High temperatures will be near or just above 50 degrees in most locations.

A light freeze is expected over at least the Missouri Ozarks tonight as weak surface high pressure moves overhead. There could even be a few upper 20s, but some high clouds are possible, which would hold temperatures up just a bit.

Our warmup begins on Wednesday with mostly sunny skies and a southwest wind, with high temperatures pushing to around 60.

Clouds may move in relatively fast on Thursday, but highs will at least reach the middle 60s. A few isolated showers or storms are possible Thursday night into very early Friday, but I think much of this activity will remain just to the West. It could get quite windy Thursday night into Friday with gulf moisture surging into the region.

Friday is now a first alert weather day with a good possibility of severe storms. There are still some model differences in timing, but dew points look to be in the lower 60s so some instability should be present period strong wind shear will also exist, and thunderstorms could fire up by mid-morning.

I anticipate this to be a fast-moving squall line with high wind being a primary threat. However, a tornado or two looks possible. Much drier air will very briefly move in for Saturday, with high temperatures back down to the upper 50s. Temperatures will quickly rebound on Sunday, and some true spring like weather should move in early next week. A nearby front, rich moisture, and temperatures near 80 degrees should trigger at least scattered thunderstorms, some of which could be severe.
