Rain Totals Fri. PM Through Sun. Midday

After 10 consecutive dry days the rain returns. This was one of our longest stretches of dry weather since July 7th-July 14th but what does it matter as we continue to add on to this record breaking wet year.

Consecutive Dry Days
Wettest Years On Record

Two areas of low pressure to our west continue to surge out of the Southern Plains while gathering rich Atlantic and Gulf of Mexico moisture.

The first low will shift in from the Missouri River Valley Friday transferring it's energy to the coast. At the same time the main low over Texas will come in from the south tapping into the Gulf of Mexico and sending moisture north toward Maryland.

The worst of the rain though looks to come in Friday afternoon with the best chance of flash flooding throughout the overnight period and then again Saturday afternoon.

Low pressure will skirt west of the the region early Sunday giving us additional lift for the rain threat to continue. Models continue to hint on a solid shield of rain Friday afternoon and evening with a lull early Saturday before another slug Saturday afternoon through Sunday midday.

The time is now to think about your flooding precautions. If you live in a low lying area remember to seek higher ground when a warning is issued. Never drive through high water since you may not know what is underneath of it or in it. The old saying "Remember Turn Around Don't Drown." A common saying that oh so many do not listen too. Please do not take it for granted since these situations look to change very quickly.

Rain should slowly depart for the Ravens home game Sunday afternoon with highs near 50 degree. Drier times shortly after that for much of next week.
