Tonight and Tomorrow...

The forecast remains on track, temperatures in the northwest have warmed to right around 70 while temps in the southeast have warmed to right around 85. Tonight the broad surface frontal system will continue to move east into Canada sending a cold front southeast towards the south central states. Northerly winds will increase as the front approaches and puts an end to rain and storm chances overnight until right before daybreak when they will begin once again centered on the ArkLaMiss borders. Going into the morning dense patchy fog will be likely to persist in the southeastern portions of the CWA as well as patchy fog being possible along and north of the HWY-84 corridor. Excess moisture and light winds will make development easy and more likely as we have seen for the last few days. Overnight low temperatures will have a wide gradient from northwest to southeast. Temps in the northwest will be seasonable in the in the low - mid 50s, while low temps in the southeast will be seasonably warm in the low - mid 60s. Throughout the course of the day tomorrow multiple disturbances moving east will have our area progged for continued rain and storm chances with a an isolated thunderstorm or two being possible./KVP/

Saturday night through late next week...

We will be cool and wet to start Saturday night and Sunday as a series of subtle shortwaves embedded within overall flow shift across the area. Expect any thunder (which should be isolated to far southern areas) Saturday night to diminish with waning instability Sunday. Not expecting a wash out with QPF totaling around a half to 3 quarters of an inch across the area Sunday. Ridging builds in the wake of a final shortwave Sunday night into Monday, shutting off rain chances. Temperatures will be noticeably cool these first few days in the extended term with highs only in the 60s and low 70s, about 5 to 10 degrees below normal for this time of year. Dry conditions will persist through the first half of next week beneath upper ridging. Mid to late next week, clouds will increase amid a warm, moist advection regime. Cannot rule out the occasional sprinkle or isolated shower at this time. By week's end, temperatures will be above average with highs in the 80s./SAS/

Aviation: IFR/MVFR categories remain at TAF sites GLH and GWO as a layer of low clouds remain, expect cloud cover to lift slightly throughout the afternoon keeping sites in MVFR cat for a majority of the period. Rain chances in Ms Delta overnight may lower categories at TAF sites GLH/GTR/GWO briefly before improving back to MVFR. All other sites will bounce from MVFR/VFR conditions throughout the rest of the afternoon into the night. Beginning around 10Z expect another round of patchy dense fog to impact southeastern TAF sites through 15Z as high moisture and low winds will make it east for fog development./KP/
