A change is finally in the air. Oh, the heat's not going anywhere just yet, but we are in for our first significant rainfall in more than a couple of weeks, and it is likely to be the heaviest rain since early July. The rain starts late Monday night. Before that happens we will have a high in the lower 70s making today the twelfth time this month that the temperature has been more than ten degrees warmer than average.
The high pressure system that gave us the warm, dry weather of the past week has moved offshore. The resulting southeasterly breeze has kicked the dew point up into the sticky lower 60s. As the humidity continues to build, a slow-moving cold front will approach from the southwest. Look for light rain tonight followed by gusty winds, heavy showers, and thunderstorms as the front draws near tomorrow. The worst of the rain will be Tuesday night, when most areas will see 1-2 inches and some places potentially seeing double that amount. Tomorrow will again be unseasonably mild with a high in the low 70s.
The rain will largely come to an end once the front passes on Wednesday morning. While the latter half of the week will be cooler it won't exactly be cold. Wednesday's high will be in the upper 60s and Thursday's will be right around the normal high of 61. Slightly warmer weather is on tap for the start of the weekend before the next cold front arrives on Saturday night.
