SYNOPSIS
High pressure will move to the east today. A cold front will move through the region Wednesday. A second area of high pressure will build back in for the end of the week.

NEAR TERM /THROUGH TONIGHT/
MID-MORNING UPDATE: Dense cirrus from early this morning has begun to fizzle out.
Some mid to high clouds are expected today, particularly west of the Blue Ridge, but coverage isn't expected to increase significantly until this evening.

The main concern today looks to be elevated fire danger. RHs this afternoon drop into the 20-30% range with sustained winds 10-15 mph and gusts 20 to 25 mph, which is favorable for drying fuels and the potential for fire spread. An SPS has been issued for the entire area from noon through 7PM.

PREVIOUS DISCUSSION FOLLOWS: High pressure will move to the east today, which will allow for our winds to turn more out of the south. This will result in a warming trend, with temperatures climbing into the upper 60s to low 70s under mostly sunny skies.

A shortwave will track southeastward from the Great Lakes toward the Northeast/Mid-Atlantic tonight. Precipitation amounts should be light given the lack of moisture. A few showers will be possible across the area, especially later tonight into early Wednesday morning.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
A cold front will move through Wednesday morning, causing winds to turn northwesterly. A gusty northwest wind of 20 to 30 mph will be possible during Wednesday afternoon. A stray shower or thunderstorm can't be ruled out behind the cold front/beneath the upper trough axis Wednesday afternoon, but most locations should remain dry. High temperatures Wednesday are expected to be in the upper 60s to near 70.

Cold advection is expected Wednesday night. Temperatures are forecast to drop into the upper 30s and lower 40s. Additional opportunities of encountering frost or freeze conditions are possible Wednesday night. Winds may be a little too high to allow for frost or freeze conditions.

Dry conditions anticipated on Thursday into Thursday night with high pressure gaining control. Thursday is also expected to be cooler by about 10 degrees from Wednesday.

LONG TERM /FRIDAY THROUGH MONDAY/
Dry conditions to end the week as surface high pressure slides east into the western Atlantic on Friday. Weak ridging aloft moves over the area Saturday. There is a chance for some shower activity, mainly west of the Blue Ridge on Saturday. However, given the combination of weak subsidence and downsloping winds (due to nearly zonal westerly flow above the surface) that mixes drier air from aloft, any shower chances look to be limited. A warming trend begins late week as highs go from low to mid 60s Friday to upper 60s to low 70s Saturday (could be higher in some areas due to downsloping winds).

Sunday into the start of next week is looking dry and very warm as deep ridging develops across the Southeast and Mid-Atlantic states.
Most models indicate a 580-585 dm ridge aloft over much of the eastern CONUS, with the Bermuda Highs building over the western Atlantic. Could be looking at near-record heat Sunday into Monday as highs reach the low to mid 80s. A weak cold front approaches from the west on Monday, possibly resulting in isolated to scattered showers and thunderstorms Monday afternoon. Very mild overnight lows in the upper 50s to mid 60s Sunday and Monday nights.

AVIATION /14Z TUESDAY THROUGH SATURDAY/
VFR conditions today through Thursday night. Winds light becoming south around 10 knots today and tonight. Winds southwest becoming northwest 10 to 15 knots gusts up to 20 knots Wednesday and Wednesday night. Winds becoming northeast Thursday, then southeast Thursday night 5 to 10 knots as high pressure builds into the region.

VFR conditions are likely Friday into next weekend. Limited shower chances possible Saturday around MRB, otherwise dry conditions are likely at the other terminals. Southeast winds on Friday become south for Saturday around 10 knots, with gusts to 20 knots possible each afternoon.

MARINE
Small craft advisories likely this afternoon through Wednesday morning for the Chesapeake Bay and Potomac River. Small craft advisories likely again for the main stem of the Chesapeake Bay Wednesday night. Winds south 10 to 15 knots gusts up to 20 knots this afternoon through Wednesday morning. Winds northwest becoming north 10 to 20 knots Wednesday night.

Southerly channeling Friday and especially Saturday could result in near-SCA conditions over the open waters of the Chesapeake Bay. This would occur during the afternoon to evening hours each day, when winds gust around 18-20 knots. Winds decrease overnight into the morning.

FIRE WEATHER
Elevated fire conditions are expected due to dry conditions and gusty winds. Relative humidity values around 15 to 30 percent are expected along with sustained southerly winds of 10 to 15 mph and gusts 20 to 25 mph. This will result in the rapid drying of fine fuels. Will continue to monitor conditions going into Wednesday, depending on how much rain actually falls with the frontal passage.

TIDES/COASTAL FLOODING
Water levels are expected to steadily increase through tonight as southerly winds push water up the Chesapeake Bay and lower Potomac River. Minor coastal flooding is likely at Annapolis during the early morning high tide cycle Wednesday, and possibly at Straits Point during that time. Most other locations will reach Action Stage during the upcoming high tide cycles through Wednesday morning.

Winds turn northwest behind a cold front causing tide levels to decrease Wednesday night into Thursday.
