It's reached the 50s across the D.C. area today after a foggy start. When will the next system return the chance for rain?

After a cool, damp and foggy start across the region this morning, skies have clear and temperatures have warmed into the 50s and 60s. High pressure will be the main story tonight and through the day tomorrow before changes enter in for Thursday. Wednesday will start off sunny but clouds will increase by the afternoon hours. Exactly when should we expect the rain to begin on Thursday and will it end by the weekend? Here's more in my latest afternoon analysis.

Concerns in the forecast: There are a few questions remaining in the forecast for the end of the week and into the weekend. The main question mark is if a coastal storm will form Friday night into Saturday. This could bring the chance for some chilly rain to the region Saturday, particularly south and east of D.C. for Southern Maryland and the Eastern Shore. There hasn't been any model consistency in this so I am not buying into it at the moment. The other question is how the weekend will be affected temperature-wise. Highs may only reach the mid 40s Saturday and the 40 degree mark on Sunday.

How much rain can we expect? here's the 5-day precipitation forecast from the Hydrometeorological Prediction Center.

Potential Precipitation through Saturday

Interesting thing to watch for: A powerful solar storm is already hitting the earth's atmosphere today and will continue tonight. There is the chance for aurora's to be seen as far south as New York and potentially even western Maryland away from all of the light pollution. This is the largest solar radiation storm since 2003.
