Isolated PM Storms, Warm

An analysis of area soundings and infrared satellite loops confirms low-level moisture has increased substantially in the last 24 hours as winds have veered around to the southeast. Satellite images show much more cloud cover this morning than I anticipated and has kept temperatures in the mid to upper 60s. The pesky upper-level low to our south will slowly move eastward today in response to another disturbance pushing southward through the Midwest. The upper low will finally have enough moisture to work with to produce slightly greater coverage of showers and thunderstorms this afternoon. However, these showers will still be isolated, and the best chance for rain will be to our south and east. Despite a few afternoon cumulus clouds, highs should top out near 89 today. It's tough to completely rule out an isolated shower overnight with an upper air disturbance moving through the area, but consider yourself lucky if you get wet. With cloud cover sticking around tonight, low temperatures in the morning will be near 69.
