Forecast Discussion

Synopsis...

A weak cold front will be passing through the state early Tuesday morning and afternoon. A cold air mass will build in behind it, keeping temperatures steady and seasonable through the beginning of next week. Aside from that, the most exciting thing to forecast for is the amount of cloud cover each day, with every day pretty much being somewhere between partly cloudy and mostly clear skies. All in all, a very boring forecast.

Short Term...

The WRF shows a weak cold front moving through the state early Thursday morning. The latest run (0Z) has the front moving much faster during the morning, so it should be clear of the eastern regions by noon. From this, the afternoon temperatures should be about 2 or 3 degrees cooler than originally anticipated. Behind this front, a steady westerly flow will build in, helping to keep temperatures mild and seasonable for this time of year basically through the rest of the forecast period. Vertical stacking of winds will allow for somewhat breezy conditions tomorrow and on into Saturday.

Long Term...

Little changes from the short term forecast... Seasonable temperatures and partly cloudy to mostly clear skies will persist through the end of the weekend and on into Monday. The WRF shows a developing shortwave late Monday night on into Tuesday morning. This may be our next rainmaker. Overall, enjoy the rest of the week and the coming Halloween weekend, because we are in for some Spook-tacular weather!
