009 FXUS64 KJAN 140301 AAA AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 901 PM CST Mon Jan 13 2025 ...New MESOSCALE UPDATE... .MESOSCALE UPDATE... Issued at 901 PM CST Mon Jan 13 2025 Rest of tonight... Clear & calm night is on tap across the region. With flat zonal flow becoming established, nearly 1030mb sfc high sagging into the area overnight & dry moisture profiles, favorable radiational cooling is expected. Lows will be seasonably cool, some 5-8F below (23-31F). Widespread frost can be expected in the morning time. Updates will be out shortly. /DC/ && .DISCUSSION... Issued at 305 PM CST Mon Jan 13 2025 Through Tomorrow: In the wake of a cold front passage today, mostly clear skies and building high pressure will set up good radiational cooling potential. It`s not the most ideal given some increased soil moisture, but we expect a widespread frosty morning with temps ranging from the lower to mid 20s in our northern zones to upper 20s/near 30 in our southern zones. Leave a few minutes extra to start your morning commute in case the windows are frosty. Then fair and dry conditions continue into tomorrow daytime as the chilly post- frontal air brings us widespread high temperatures in the lower to mid 50s. /NF/ Wednesday through Monday: SFC high pressure will build into the lower MS-River valley and remain through much of the work week. Dry conditions are expected until late Thursday into the weekend ahead of an approaching cold front. As mentioned above, chances for rain return Thursday as zonal flow aloft weakens and a series of disturbances swing through the area steadily increasing rain chances through the weekend. Between Saturday night and Sunday afternoon a strong cold front will sweep through the area from the northwest limiting rain chances to mainly the southeast to begin the next workweek. Temperature wise can expect temps to warm gradually to well above climo with low temperatures >10 degrees above climo by Saturday as strong southerly wind-flow prevails across the area. Following the passage of the cold front winds will become northwesterly as strong arctic air plunges into the region. Once again, we will see highs warming to just above freezing by Monday, and low temperatures in the 20s. There is a low chance for some wintry precip Sunday night into Monday as precip chances overlap the period of coldest temps. This is still a week away, so be sure to stay updated with the forecast this week. && .AVIATION...
