Issued at 1120 PM CST Mon Feb 2 2026 - Rain chances will affect the Mid-South on Tuesday. Light and steady rainfall will accelerate the melting of ice and sleet across most of the region. - Dry and below normal temperatures will return for Wednesday and Thursday with temperatures dipping back down below freezing each morning. - Dry and slightly above normal temperatures are expected Friday through the weekend. && .DISCUSSION... (Tonight through next Monday) Issued at 1120 PM CST Mon Feb 2 2026 The latest surface analysis places a 1014mb low over Oklahoma with a stationary front strewn across north Mississippi. Regional airport observations show mainly light to calm conditions across the Mid-South with 5 to 8 degree dewpoint depressions. GOES East Nighttime Microphysics RGB reveals a broad area of cirrus overspreading the region from the west. The aforementioned stationary front will lift north overnight as the surface low takes an east-northeastly track into southeast Missouri. A cold front will move into the region Tuesday morning and slowly track east across the region through Tuesday night. HREF guidance suggests nearly the entire Mid-South will see rainfall, with the highest precipitation totals along and east of the Mississippi River. Above-freezing temperatures and rainfall will promote the melting of residual snow, sleet, and ice across the region from nearly 9 days ago. A shot of polar air is expected Wednesday and Thursday as a 1034mb high builds in across the Mississippi Valley. Temperatures will dip 10 to 15 degrees below normal once again with subfreezing temperatures each morning. Thursday will be the coldest with lows dropping into the teens across much of west Tennessee and north Mississippi. Temperatures will rebound quickly on Friday as a warm front lifts north across the region and upper level heights build. Above normal temperatures are anticipated this weekend as upper level high pressure remains over the region. NAEFS ESAT tables show that 90th percentile 500mb heights will likely continue through the middle of next week, keeping above normal temperatures and dry conditions in place across the Mid-South. && .AVIATION... (06Z TAFS) Issued at 1120 PM CST Mon Feb 2 2026 Conditions will slowly deteriorate through sunrise as a frontal boundary sinks across the Mid-South. LLWS of 40kts and showers will develop by 13Z and impact all terminals. As this activity pushes east, there is medium confidence in IFR/LIFR CIGs developing. Precipitation will exit the area by 00Z with conditions slowly improving thereafter. ANS && .FIRE WEATHER... Issued at 1120 PM CST Mon Feb 2 2026 Fire weather conditions are not anticipated this week due to light winds, minimum relative humidities above 45 percent, and wet fuels. Wetting rain is expected Tuesday along and south of I- 40. Subfreezing temperatures will return Wednesday and Thursday with a warming trend through the weekend. && .MEG WATCHES/WARNINGS/ADVISORIES...
