Synopsis
High pressure will slide offshore today with a warm front lifting north through the region. A cold front will approach from the west tonight then cross the area late Monday and Monday night. High pressure will build in mid week.

Near Term - Until 6pm This Evening
As of 940am Sunday...Mid level clouds are moving off the coast this morning, as a stalled front remains to the south. The front will return north today as high pressure slides offshore, with increasing southerly flow through the day. Highs expected into the low to mid 80s inland, and the mid to upper 70s closer to the coast.

Short Term - 6pm This Evening Through 6am Monday
As of 3am Sunday...Cold front will approach from the W keeping area firmly in warm sector with cont SSW winds that will remain strong near the coast. Moisture will increase a bit thru the night but for now looks like will remain dry...did increase pops northern tier to just below slight chance as cpl models shows spotty shra possible twrd daybreak. Lows will be mainly in the 65 to 70 degree range.

Long Term - Monday Through Saturday
As of 330 Am Sunday...Another fairly active pattern through the week: strong cold front approaches Monday, building high pressure midweek leading to a late-season CAD event, and another weak shortwave trough to affect the area to end the week.

Monday...SFC low just off the New England coast swings its cold front through the area late in the afternoon, increasing the likelihood of rain and chances of thunderstorms ahead of the front in the afternoon into the evening. Highs Monday are the warmest in the period reaching the mid 80s. Marginal Risk for severe weather is in place with decent moisture ahead of the front, good forcing, and heating allowing moderate instability to develop throughout the day. Moderate shear indicates the ability for semi-organized storm clusters to develop. Damaging wind gusts and hail are the main threats with this event. Showers behind the front linger and potential for thunder becomes limited to the frontal boundary as it crosses coastal areas overnight.

Midweek...The cold front stalls well to our south through midweek with high pressure building in from the north setting up a late-season CAD event keeping temps cool, highs in the upper 60s/low 70s and lows in the upper 40s and low 50s. Guidance is catching on to the CAD event and subsequently are trending their temps down. Have kept temps on the colder side of trusted guidance but have not gone as low as some of the extreme outliers.

Thursday And Friday
High pressure shifts offshore the VA coast overnight Thursday. Guidance has backed off on the deepening of a coastal low and instead are showing weak shortwave troughing further south and not deepening the system until it is well offshore of SC. Probability of Precipitation was lowered a bit to reflect this. Thunder was removed from the grids for now with instability being severely limited.

Weekend...Drying trend with temps warming back up, highs reaching the 80s by Saturday.
