After an upper-level feature (some people may call it a secondary cold front or a trough) moves through the region Thursday morning, high pressure begins to build in and it will last through Friday. Thus, we will see lots of clouds Thursday morning and more in the way of sunshine Thursday afternoon.
Temperatures will be fairly chilly, though not far from seasonable levels in all actuality. What we will notice is that temperatures will not rise a heck of a lot even with strong, almost April sunshine working on the lower levels of the atmosphere in the afternoon. This is due to a decent amount of cold air advection.
Thursday night we will see a few clouds around, but the main story is that it is another great radiational cooling night.
High pressure remains in control for Friday, though we will see clouds increase during the afternoon as a rapidly moving area of low pressure approaches from the west. Temperatures will remain on the chilly side as we are locked in a cool air mass.
Low pressure approaches the region Friday night, tracking right on top of the area. There is a decent slug of moisture associated with this low, so expect a good dose of rain, just what the area needs to reduce the fire danger and increase the soil moisture content. The rain should begin fairly early in the evening.
