Synopsis
High pressure slides off the Carolina coast late today through Wednesday. Shower chances increase Thursday through Saturday as a couple of low pressure systems impact the area.

Near Term - Until 6am This Morning
As of 630pm EST Monday... Winds have decreased inland but remain gusty near the coast for the next few hours before falling off later tonight into Tuesday AM. A few clouds hanging on over portions of the MD Eastern Shore but skies are expected to be mostly clear tonight. Made some minor tweaks to temps and dew points to better match observations. Lows tonight generally in the upper 20s to low 30s.

.SHORT TERM /6am THIS MORNING THROUGH THURSDAY/... As of 215pm EST Monday... Ridge aloft amplifies INVOF SE CONUS while surface hi pressure sets up off the coastal Carolinas through Tue. A dry/mild day Tuesday w/ SW winds to about 10 mph. Leaning towards the higher temperature guidance...wouldn't be surprised if readings ended a few ticks higher...esp over Central VA. Highs from the m50s on the ern shore to the u50s-l60s elsw. A weak trough aloft and surface cold front cross the region late Tuesday night through Wed. Patchy clouds/no precipitation expected. Milder Tuesday night w/ lows in the l-m40s. Warming up Wednesday w/ SW winds shifting WNW and no worse than partly sunny. Highs in the m-u60s...slightly cooler near the coast/on the eastern shore. Winds shift to SSE Wednesday night as weak surface hi pressure shifts to off the coast. Lows in the m-u30s on the ern shore to the l-m40s elsw. Lo pressure tracking into the Great Lakes pushes weak trough aloft/surface front towards/into the region from the W by late Thu. Will follow the blended guidance for PoPs...30-50% NW to 10-205 SE. Highs in the l-m60s at the coast...u60s-around 70F inland.

Long Term - Thursday Night Through Monday
As of 115pm EST Monday... A mostly unsettled period of weather from late week through the Sat. Mild/warm Thu night through Fri...then colder (back to normal) Sat-Sun...then becoming milder again early next week. Lo pres tracking INVOF St Lawrence River Valley Thu night-Fri pushes a weakening cold front into/through the FA. Probability of Precipitation diminishing Thu night then amplifying trough aloft through the Ms River Valley Fri results in a second wave of lo pressure to develop INVOF ern gulf states then track NE. Probability of Precipitation to increase by Fri afternoon (rising to 50-60% NW to 70-80% E and SE) then continue Fri evening before tapering off Fri night as that second wave of lo pressure tracks through the FA and eventually to off the NJ coast. Fairly strong trough aloft to bring VRB clouds/mostly cloudy-breezy weather Sat along w/ lo Probability of Precipitation as low level Cold Air Advection takes place. Hi pressure and dry returns for Sun-Monday as ridge aloft rebuilds INVOF SE CONUS. Seasonable Sunday then milder Mon.

Lows Thu night from the l50s NW and on the eastern shore...to the m-u50s in between. Highs Fri in the m-u60s...slightly cooler on the eastern shore. Lows Fri night from the u30s W and N to the l40s SE. Highs Sat from around 50F W to the l-m50s elsw. Lows Sat night in the m-u20s inland...mainly l30s at the coast. Highs Sun from the m-u40s on the eastern shore to the l50s most other areas. Highs Monday in the m-u50s on the eastern shore to the u50s-l60s elsw.

Marine
As of 230pm EST Monday... This afternoon, rapidly strengthening low pressure is located well off the Mid Atlantic coast and is quickly moving off to the northeast. Meanwhile, high pressure centered over the Great Lakes is building into the local area. As a result of the tight gradient between the building high and low offshore, it has been quite breezy this afternoon over the waters with a stiff NW wind around 15 to 25 knots with gusts to around 30 knots at times. Small Craft Advisories remain in effect for all waters (outside of the upper rivers where we have a MWS for wind gusts to 20 knots) until at least 7 PM. SCAs (Small Craft Advisories) remain in effect for the coastal waters until 10pm for the VA/MD waters and 7am for the NC waters due to lingering 5 foot seas.

Winds rapidly diminish later this evening into tonight as high pressure becomes centered just to the west of the local waters. Winds of around 5 to 10 knots are expected late tonight into Tuesday morning. Winds briefly increase to around 10 to 15 knots and become SW Tuesday afternoon into Tuesday night as a weak front crosses the region. In addition, seas will be building to around 5 to 6 feet (especially out 20 nm) Tuesday afternoon into Wednesday due to swell from the departing low pressure system. As a result, additional SCAs (Small Craft Advisories) will likely be needed for 5+ foot seas for the coastal waters. Winds will range from 5 to 10 knots on Wednesday as high pressure briefly returns. Another strong southerly surge is expected late Thursday into Friday ahead of our next storm system, leading to another period of potential SCA (Small Craft Advisory) conditions (especially for the Chesapeake Bay).
