10/25 – Rob’s Wednesday Morning Forecast

As high pressure to the NW continues to move SE…the warming trend will begin later today as winds will begin to switch to the W/SW overnight. The next system will move out of the Rockies Thursday and into the Mississippi River Valley on Friday. Onshore flow returns Thursday evening, which will aid in the development of precipitation by Friday afternoon. Main jolt of showers and thunderstorms will be overnight Friday night, near and just behind the associated cold front. Rain potential will begin to increase as early as Friday morning with the majority expected overnight into Saturday morning. There`s a SLIGHT THREAT for a few t-storms to become SEVERE Friday night, but with the timing of the front moving through the area…this threat seems to be on the decrease.

Due to the cool start this morning, daytime highs will likely fall a little short of what was seen on Tuesday. With the passage of the upper trough this morning, overnight lows tonight won`t be quite as cold as this morning. As winds shift to southerly on Thursday, temperatures will respond accordingly with highs near 80 degrees over SE Louisiana and mid 70s on the Mississippi coast. Temperatures will then remain above normal until frontal passage. We will trend toward the warmer high temperature guidance in the short term. Low temperature guidance is fairly consistent, and won`t stray very far from it.

Precipitation will linger into Saturday morning behind the cold front. Beyond that, remainder of the extended forecast period will be dry as flow becomes more zonal across the southern states. Saturday will be an uncomfortable day, as it will take most of the day for clouds to depart. Northwest winds around 15 mph will combine with temperatures near 60 degrees to make things feel considerably cooler than we’ve seen in about 6-7 months. Overnight lows Saturday night are likely to be in the mid and upper 30s across at least the northern half of the area. In areas well protected from wind, it`s not out of the question that a little frost could occur Sunday morning. From Sunday onward, temperatures will moderate with readings eventually returning to above normal levels for highs by midweek next week.
