Overall the clouds will be remaining tough this afternoon keeping things fairly stable. However, showers will begin to crop up late this afternoon in eastern Texas, becoming numerous this evening. Steep temperature lapse rates associated with the approaching cold core upper low will make large hail our primary initial threat this evening and overnight as the front moves Southeastward. However, damaging winds and possibly isolated tornadoes will become possible as scattered thunderstorms organize into bows and perhaps even a squall line in the predawn hours. This line will quickly move across our Louisiana parishes just after daybreak. Brief heavy rainfall will be possible with rainfall amounts ranging from a half inch to inch for most of us with a few sites near 2 inches along and South of I-20. The cold front will be arriving before daybreak with rain showers changing to some snow showers before ending North of I-30 during the morning hours. Wintry impacts are not expected for us with the much warmer ground temperatures, but travelers farther North should plan for such. Also, everybody secure objects today for Windy conditions coming. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Gusty high pressure gradient winds will move in with this Arctic cold front early on Saturday. Expect northwest winds of 20 to 30 mph with higher gusts to near 40 mph, not to mention the quickly falling temperatures immediately behind the front moving across I-30 before sunrise. These gusty winds will spread Southeastward from daybreak to Noon across the rest of our cwa. High temps will occur before lunch almost everywhere and thirties will cover our entire area before sunset with clouds clearing out. Then we can expect freezing temperatures Saturday evening and all night long with still very cold wind chill readings. A range of low to mid twenties will greet the day on Sunday as the winds begin to relax. The cold air mass moves East early in the new week with a warmer trend and quickly wetter trend with showers and thunderstorms on Tuesday and night ahead of our next Arctic blast early on Wednesday. Rinse and repeat forecast with freezing temperatures by Thursday morning. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators and storm spotters may be needed this evening and overnight ahead of this Arctic blast coming in the morning. 24
