Best Rain Chance Tomorrow; Closely Watching the Tropics
4:30 p.m. Thursday 25 August 2016
The flow around a large upper high centered to our east will push an upper-level impulse into Texoma tomorrow. This feature provides lift, so even by late morning scattered showers and thunderstorms may form. The coverage should be highest in the eastern half of our area, but all sectors have a chance for rain tomorrow.
The activity increases with daytime heating, but severe weather is not expected. Heavy rainfall and lightning can be expected in the stronger storm cores. Some back yards may get one-inch plus rainfall totals but these will be in pockets with other locations receiving little rainfall.
As for the first week of Friday night football, the bulk of the action should fade away by sunset; leaving just a 20 percent chance of the actual game getting wet. We’ll have a secondary round of showers on Saturday but with much reduced coverage as the impulse begins to weaken.
Out in the Atlantic, a low-pressure area over the southern Bahamas could develop into a tropical storm or hurricane as it makes its way toward Florida. The future of this system is somewhat murky as it’s still in a stage of limited development. The most likely scenario is for it to affect Florida and possibly the eastern Gulf during the next week, but have little effect here.
Upper level high pressure will keep things a bit hotter than average next week but no triple digits.
Here are the numbers:
Overnight: Clear to partly cloudy…Lows 70 to 74
Friday: 30% Storms west to 60% east …..Highs 92 west to 87 east
Saturday: 30% Showers/storms…..71/93
Sunday: 20% Showers….70/94
Monday: 20% Showers…..71/94
Tuesday: Mostly sunny…..71/95
Wednesday: Mostly sunny…..71/95
Thursday: 20% Showers…..71/94
