It is hard to believe that September is nearing an end and we will be welcoming October very shortly! Lately, the weather has been cooperating with wall-to-wall sunshine and comfortable temperatures! So far this month, we have received 2.53" of rain at BWI with September 17th being the last day with measurable rainfall of .14". We are still slightly below average from the normal value of 2.89" for the month.
There is still seven more days left in September so rainfall totals have time to add up. There is a great deal of moisture situated to our southwest around Mississippi, Arkansas, Tennessee, and Louisiana--the remnants of Beta.
The pleasant weather across the Mid-Atlantic region will come to an end as the remnants of Beta track northeast later this week. On Friday, computer models are showing the moisture residing to the south of the metro around southern Maryland and Virginia. The exact placement of rain is still a bit uncertain--allowing expected rainfall totals to be uncertain as well. It just depends on how far north the rain travels, but the bulk of the rain looks to stay to the south of I-95. It is looking likely that higher rainfall totals will be measured to the south of BWI.
The remnants of Beta will move offshore early Saturday allowing for more dry time Saturday afternoon. There are a couple cold fronts that will move through the region during the tail end of the weekend and early next week, which will add to our rainfall totals for the month as well.
