Rain Chances on the Rise

By Jay Grymes & Steve Caparotta


Our forecasted run of “drier” weather looks like it might be ending a little more quickly that we thought yesterday, when we called for very limited rain chances for today and Wednesday. Although today’s rains were very limited (as expected), the guidance for Wednesday has become a bit “wetter.” We’re now going with scattered showers and storms for Wednesday (a 30% to 40% rain chance for your neighborhood) instead of the isolated rains we anticipated yesterday.

But the remainder of the forecast through the rest of the work week and the weekend remains essentially unchanged at this point. Look for scattered, mainly-afternoon showers and storms for Thursday and Friday (40% probabilities for both days), with 50% to 60% rain chances posted for Saturday and Sunday. Rain coverage should slacken a tad early next week.

On the national scale, heat-related warnings, watches and advisories are posted over much of the nation’s northeastern quadrant today, with highs approaching 100° or more from the mid-Mississippi Valley into the Ohio Valley. 





Closer to home, we continue to watch the mid/upper low spinning to our east. Yesterday the system was located just off the Georgia/Florida Atlantic Coast, but as we mentioned, it has worked its way to the west. As of today, the low is centered along the Georgia/Florida state line and continues to move west. The thinking at this time is that the system will weaken and essentially dissipate before it comes as far west as Louisiana, but it is still worth a watch. In any case, there is no concern for this to change into something more “tropical.”

And in the tropics? All remains rather quiet across the Atlantic Basin.
