It is foggy (visibility as low as 0.50 mile in places) & drizzly out with approaching cold front.  It will pass this evening & winds will turn to the northwest & gust to 30 mph.  A few spotty rain & snow to a few spotty snow showers & flurries are possible with it.  Temperatures will drop to near 25 tonight with wind chills around 14.

Thursday looks dry with just a lot of clouds with some sun.............same for Friday.  Highs will run 34-40 Thursday, 37-44 Friday.

Thursday night-Friday morning's low will be determined by how much widespread clearing we see.  I am basing the 17-21 low on the clearing, but if more clouds hang on for part of the area, then those areas will not get as cold or see frosty conditions.

Here is the Friday night-Sunday storm system. 

It will be strong!

Saturday will be rainy & windy, but timing of heaviest rain & narrow squall line of storms & warmth is speeding up.

The viewing area will likely experience the high temperatures of 57-64 in the 8 p.m. to 12 a.m. time frame ahead of that northeastward-racing QLCS squall line. A couple isolated severe storms are possible in the line.  A couple isolated severe storms are possible here Saturday evening with brief EF0 tornado &/or a couple severe gusts possible.  It will be a low CAPE, highly-sheared & dynamic environment, typical of the cooler season.

Severe weather outbreak is likely southern Indiana to the Deep South.

All severe weather is on the table with the potential of a few strong/long-track tornadoes. The best potential of that seems to be centered over eastern Texas to Arkansas, Louisiana, Mississippi & western Tennessee.

Rain will exit (1-2.25" possible), followed by dry slot with some clearing after midnight Saturday, but low clouds will have already filled back by Sunday morning with howling northwest winds.

The winds look like a big issue late Saturday night-early Sunday with peak gusts of 40-55 mph possible with sustained winds 15-30 mph.  Wind Advisory will likely be issued.  Part of the area could be upgraded to a High Wind Warning if data become more consistent with some +55 mph gusts.

Blizzard is likely Kansas to Iowa to southeastern Minnesota to Wisconsin with complete white-out & gusts to 55-65 mph Saturday, Saturday night to Sunday morning.

Some scattered rain/snow to scattered snow will pivot through Sunday with falling temperatures & howling northwest winds at 35-50 mph at times in the afternoon (after winds peak in the early morning).

Some snow/mix is possible late Monday to early Tuesday, then a few showers. That all look inconsequential. Much colder air will then roar in on howling northwest winds with highs on Wednesday around 20 degrees below normal.

Some snow is possible Wednesday-Thursday of next week & again on Saturday (March 2).
