SCATTERED STORMS ON THE WAY!

As high pressure continues to slip off to the east, it will allow fairly week upper level disturbances to affect East Mississippi and West Alabama. On this Tuesday night, an upper level low is centered across the Southern Plains; however, as this system lifts to the northeast it will have very little impact on our weather because most of the rainfall will stay to the north and west of the Twin States. So Wednesday will be for the most part dry with very warm temperatures continuing. By the way, today we hit a high of 88° at Key Field in Meridian which gives us our warmest day of the year so far. I will hold out for a 10% chance of an isolated thunderstorm or two on Wednesday, but the best chance of rain will stay to the west of Interstate 55. By late Wednesday, another upper level disturbance should be moving into West Texas, and this system will continue to move off the the east on Thursday. With our warm and moist atmosphere in place, as this disturbance approaches our area scattered showers and thunderstorms will be on the menu for Thursday and Friday.

The above map was generated by the GFS Model at 12Z (7:00 a.m.) this morning, and it is showing precipitation for 0Z Friday which is really 7:00 p.m. Thursday. And just so you know what you are reading here is a little guide taken from Unisys Weather. (The quantitative precpitation field shows estimated 12 hour precipitation (liquid equivalent) for the 12 hour period prior to the valid time). So it basically shows rainfall rates below a 0.25" across the area from 7 a.m. Thursday through 7 p.m. Thursday. However, isolated rain totals could approach 0.50" or even higher with stronger storms. Severe weather is not anticipated at this time, but any storm that develops may produce gusty winds, brief heavy downpours, and frequent cloud to ground lightning. We need the rainfall because we are 14.43" behind for the year.

God Bless
