Wednesday Evening Map Discussion

Zzzzz... that's been the weather so far this week. That continued today, where highs ranged from upper 80s to low 90s. Changes are on the way though, as a cold front again will begin to slide into the area.

Here's a look at the 18z NAM model valid at 7 pm July 4th:

I've drawn in the location of the cold front with a gray/grayish purple line to our north. This will be close enough to kick off mainly afternoon and early evening thunderstorms. At this time, there will no widespread severe weather, but there will be locally heavy rain and frequent lightning. Keep an eye to the sky as your festivities get going in the afternoon. When you hear the thunder, it's time to move indoors.

The second item I've circled is a blob of tropical moisture in the western Gulf of Mexico and Bay of Campeche. We'll have to keep an eye on that to see if it moves inland, which would lead to more numerous showers and thunderstorms.

Next update comes tomorrow evening.
