Mild conditions will persist through tonight with an increase in cloud cover and humidity overnight. Tomorrow we will begin the transition to a more active pattern - a low pressure system will approach the area tomorrow morning, and rain is expected to begin around 6am in southeast Alabama and gradually spread eastward through the morning. Plenty of moisture and warm conditions will provide fuel for some thunderstorms, a few of which could be strong to severe. The threat for severe weather is generally low, but the best chances will be from late morning (in SE Alabama) through mid-afternoon (Big Bend) tomorrow, especially near coastal areas. The greatest threat with any severe storms will be damaging winds.
A secondary system will form over the Gulf Sunday night and keep rain chances in the picture through Monday evening; widespread rainfall totals of 2-4” are expected, with some localized areas seeing up to 6+ inches. The long duration of rainfall and saturated airmass will create a flooding threat for area rivers and streams – many could approach bankful or action stage, so advisories should be monitored and caution should be used near Big bend waterways this week.
A drier airmass will make its way in on Tuesday and will persist through the remainder of the work week. High temperatures are expected to be seasonal in the low to mid 70s, with lows expected to be in the high 40’s and low 50’s. Cloudiness on Tuesday will make way for mostly sunny skies on Wednesday and Thursday, the first official day of spring.
