Technical Forecast Discussion

Short term (Wednesday 10/17 through Saturday 10/20)

An upper level trough will begin the exit the region starting on Wednesday. A closed high pressure system will be off to the west, so clear conditions continue. The seasonal cool weather trend looks like it is here to stay as temperatures will stay in the 50s for the length of the long term forecast. A dry cold front will push through tonight with high pressure lurking behind it. With CAA tonight and radiational cooling, frost is likely to be widespread tomorrow morning as lows will be around the low 30s. Ridging moves in on Thursday as clear conditions continue. Skies remain clear as Thursday night will lead to another possibility for frost on Friday morning. A negatively tilted trough approaches late Friday into early Saturday with a cold front leading it. Showers will persist through Saturday night. Moisture comes through in two forms. One from the incoming cold front, and another later on Saturday associated with a secondary cold front behind the one from Friday. Precipitation totals are possible around a quarter of an inch. High pressure looks to move in later Saturday, leading to a clearing of clouds and rain for Sunday.

Long term (Sunday 10/21 through Tuesday 10/23)

Upper level troughing deepens as the axis exits the region on Sunday, putting the area in the downstream portion of the trough. The secondary cold front on Saturday will bring another batch of cold, dry air through the region as skies remain clear. Southerly surface flow exists on Monday that will bring slight WAA into the region as highs slowly climb up into the mid to high 50s. High pressure over the Virginias will also serve to continue the trend of clear skies and calm conditions. Heading into Tuesday, a ridge can be seen strengthening over the Central Plains. This will bring localized high pressure and relatively barotropic condition’s that serve to continue clear conditions into the later half of the work week.
