MESOSCALE UPDATE

Issued at 932 AM CST Wed Nov 4 2026

Latest surface analysis had the cold front over east Mississippi. Temperatures along and ahead of the front were running in the mid 70s while behind the cold front temperatures were running in the low to mid 60s. Latest satellite imagery showed the clearing line already east of the Mississippi river. As the cold front continues shifting east today, the light rain will end and the clouds will clear from the west. /22/

DISCUSSION

Issued at 201 AM CST Wed Nov 4 2026

Today and Tonight...

The cold front responsible for showers and storms overnight and into this morning will be shifting east across the area today, clearing the Pine Belt by early afternoon. In its wake, cooler and drier air associated with building high pressure will signal an end to rain chances and the period of warmth and humidity we have recently experienced. Highs today will be a bit lower than yesterday for most, topping out in the lower 70s F northwest to near 80 F in the southeast. Lows tonight, however, will be much chillier, dropping down into the 40s F for most to near 50 F in the Pine Belt.

Thursday through early next week...

While the pattern will be substantially more suppressed heading into the weekend with high pressure and continental air largely in control, an active southern stream jet will provide for an opportunity for increased cloudiness and perhaps an isolated shower or two through early next week. Overall, though, most locations will stay dry and those that do see a brief shower won't see much. The next 7 days will likely be dry and cool as overnight lows average 5 to 10 F below climate normals for this time of year.

Lows temperatures at times will flirt with the mid to lower 30s F, particularly in some of the typically cooler spots. This could result in some chance for a light frost though most places likely manage to stay above freezing. The coldest night appears to come Sunday night before we begin a slow moderating trend (lows "only" down into the lower 40s F) into the middle of next week. Regardless, these near-freezing temperatures serve to remind that now is a good time to begin practicing those winter safety practices. Ensuring plants, pets, and people are considered for as nights begin to more routinely threaten frost/freeze. /86/
