After a few days of unsettled, rainy weather, we have shifted to a stretch of pleasant and dry conditions. As a cold front exits south of the area, dry air has swooped in. This morning's sounding compared to yesterday mornings shows PWAT values dropping form over 2" to just above 1". Temperatures this morning were also slightly cooler with many in the mid to upper 60s. Tomorrow morning, lows will dip a little lower with low to mid 60s expected, possibly even some isolated upper 50s in the northern areas. Conditions will remain unchanged through mid week as high pressure holds over the region. Moisture slowly returns Thursday with rain chances reappearing in the forecast over south Florida as a cold front approaches the area. Highest rain chances through the end of the week into the weekend will likely remain south of I4. Following the front, the northeast winds will pick up, helping to push more dry air in over the area as next week begins.
