Slightly Cooler, Less Humid

A weak cold front that sparked a few scattered showers and thunderstorms yesterday has pushed into South Mississippi. It doesn't seem that the weather has changed as temperatures remain muggy this morning despite the frontal passage. However, much drier air will filter into the area via northwesterly winds throughout the day, and dew points could even drop into the upper 50s later this afternoon. Additionally, an upper air trough located to our northeast has caused temperatures above the surface to drop almost 8 degrees compared to low level temperatures for much of the last week. This should allow temperatures to top out near 90 this afternoon. Skies should be clear this evening with dry air and light winds, and this combination should allow for temperatures to drop to 63 tomorrow morning. That's about as crisp as it gets for summertime! The upper air trough to our northeast will deepen later this week and could yield a few surprises in the rain and temperature columns. Regardless, don't get used to the slightly cooler temperatures and low humidities because a classic summer heat wave may take shape after the middle of July.
