A strong mid-level shortwave trough will move across the area ahead of a low pressure center, with strong upper divergence moving across at the same time. Looking at the latest run of the NAM 4k model, it is actually keeping any organized rain away until after 3-5PM timeframe. There is a chance of some shower or thunderstorm development before that time. I’m going with partly to mostly cloudy skies with a chance of showers and thunderstorms before 3PM, with rain chances increasing afterwords. Highs will reach the upper 60 to close to 70. Winds will be out of the southwest at 5-10 MPH. Chance of rain is 60%. Expect rainfall amounts up to 1/4 inch, even more possible in thunderstorms.
The shortwave trough will linger around the area and will get reinforced by a vort max from Canada on Friday night. A low level jet will join in the action and allow warm air advection to move in. Hopefully by Saturday morning, most of the energy from all of this will have moved out of the area. Unfortunately it looks like cloudy skies and a chance of rain will persist thought the day. Some thunder could be possible before 1PM. Highs will reach the middle to upper 60s. Winds will be out of the southeast at 5-10 MPH, becoming out of the east in the afternoon. Chance of rain is 60%. Expect rainfall amounts up to 1/4 inch, even more possible in thunderstorms.
Radar is up and running on our website at www.RacecastWeather.com. I’ll have updates on my Twitter feed @RaceWx4You. Let’s hope I am way wrong with this forecast. I’d rather bust and it be dry, than to be correct and be wet.
