Small Craft Advisories for Chesapeake Bay and the Lower Tidal Potomac were extended through the day Wednesday. .KEY MESSAGES... - 1) Dry conditions and seasonable temperatures are expected through early next week. KEY MESSAGE 1...Dry conditions and seasonable temperatures are expected through early next week. The pattern will remain relatively stagnant for today and tomorrow, with a Nor'easter continuing to circulate off the Mid- Atlantic coast and high pressure gradually building to our north. Northerly winds will continue to advect dry air into the region, leading to sunny skies during the day and clear skies at night. Temperatures will be near seasonal normals, with highs in the 60s to near 70 and lows in the mid to upper 30s (west of the Blue Ridge) to lower to middle 40s (east of the Blue Ridge). By Thursday, what remains of the upper reflection of the offshore closed low gradually becomes absorbed into a deep trough over eastern Canada. These adjoining features are slated to pull eastward into the Canadian Maritimes while upstream heigheights build across the Mississippi Valley. From Friday and into this weekend, this broad ridge axis advances eastward ahead of a trough inhabiting the western/central U.S. As this occurs, there are some hints of another upper low center getting pinched off near the Carolina coast. However, its far southward displacement should minimize any direct impacts from this system. Overall synoptic uncertainty does increase markedly toward the end of the weekend and into early next week. Most notably, it revolves around a split in the jet streams over the middle of the continent. Looking down at the surface, high pressure dominates through late week while becoming more centered over the northeastern U.S. by Saturday. This ensures continued tranquil weather heading toward the last week of October. Expect dry conditions along with abundant sunshine each day. The air mass will remain quite dry owing to the prevailing northerly component to the local wind fields. Most days should yield highs in the 60s (50s for the mountains). The coldest overnight periods will likely be Friday and Saturday nigheights as lows fall into the 30s to low 40s. With the growing season having ended from the Blue Ridge westward, it remains to be seen if any frost/freeze threats emerge off to the east. Marine Persistent northerly flow is expected to continue over the waters through Thursday as a Nor'easter continues to circulate offshore and high pressure gradually builds to our north. Small Craft Advisories remain in effect for the Lower Tidal Potomac and Chesapeake Bay through the day Wednesday. Expect a northerly wind to largely dominate through Friday before turning more northeasterly by the night. Small Craft Advisories may be needed on Thursday, but particularly by late Thursday into Friday morning given a northerly surge in the winds. Tides / Coastal Flooding A Nor'easter will continue to circulate offshore through Thursday as high pressure builds to our north. This will lead to persistent northerly flow over the waters. Minor flooding may be possible at many tidal sites tonight through the day Thursday, but some uncertainty still remains.
