&& .NEAR TERM /THROUGH SATURDAY/...
-- Changed Discussion --
Cumulus has developed over central sections of CWA this afternoon. Regional radars showing echoes over this same area but with cloud levels around 10kft do not think much is reaching the ground. Webcams around the area confirm this to be the case with dry boundary layer. Have removed thunder from the forecast as well. For tonight, skies should late this evening with temps dipping down toward 40F acrs the north. Airmass warmer than last night so not expecting any frost overnight acrs the area. Mostly sunny skies expected on Saturday with deep mixing up toward 750mb in the afternoon. This will likely result in northerly winds gusting toward 20mph. Temps will be near seasonal norms with highs around 70 and into the lower 70s over most locations.

&& .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
-- Changed Discussion --
Quiet weather from Saturday night through Monday. A blocked upper level pattern persists, with an upper level low pressure remaining parked to our east just south of Nova Scotia, while an upper level ridge of high pressure remains centered just off to our west. This puts us under dry northerly flow. Dry Saturday night through Sunday night with mostly clear skies, and too much subsidence Sunday for any diurnally driven showers. Warmer on Sunday with highs in the mid 70s to low 80s, but dewpoints will still be low (in the 40s), so it will still feel comfortable. Perhaps a few afternoon showers on Monday as a weak vort max rotates NE to SW around the upper level low to east, with a bit more afternoon instability. Still, generally went with only 20 percent PoPs. Still warm Monday with highs in the mid 70s to 80s. Dewpoints up a touch from Sunday, but still reasonable with generally low 50s. Fairly light winds the whole period Saturday night through Monday. Models in good agreement. Main item of uncertainty is how many showers are able to form Monday afternoon.

&& .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
-- Changed Discussion --
Upper level ridge that had been centered just off to our west moves roughly over the state Tuesday/Wednesday. While we can`t rule out isolated afternoon showers, the weather should remain quiet with above average temperatures and a good amount of sun. Ridge slowly breaks down toward Thursday/Friday, but model agreement falls apart as to how fast and dramatically the ridge breaks down. The general model trend has been for dry weather hanging on longer than before. We could see some increased shower activity Thursday, but more likely it should hold off until Friday.
