Marine Weather and Tide Forecast for Lake Murray of Richland, SC

NEAR TERM /THROUGH TONIGHT/
Key Message(s):

- Dry and warmer today, although temperatures remain below average.

High pressure is in place across the forecast area and we are warming up quite nicely after our chilly start. Under sunny skies, temps have moderated into the upper 40s and should continue pushing into the low 50s this afternoon. We remain bone dry, with widespread dewpoints in the mid to upper teens. Clouds will remain at a minimum until potentially late tonight when some high clouds may stream into the far southern FA as upper level ridging begins to approach the area. Lows tonight are expected to moderate by 10F or so, falling into the low or mid 30s.

SHORT TERM /SUNDAY THROUGH TUESDAY/
Key Message(s):

- Transition to a warmer and wetter pattern through mid week

A shortwave upper ridge will pass over the Southeast U.S. on Sunday which allows temperatures to warm back to near normal for early December. This feature moves offshore Sunday Night through Tuesday and is replaced by southwest flow aloft. A series of shortwave troughs are expected to move over the departing ridge and bring scattered to numerous showers to the region. High temperatures are expected to be five to ten degrees over normal on Tuesday. Rainfall accumulations during this time period should range from one third of an inch east to an inch west.

LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/
Key Message(s):

- Wet, warm, and breezy Wednesday - Drier and colder later in the week

A deep and powerful upper level trough moves from the Lower Mississippi River Valley Tuesday Night to off the East Coast by late Wednesday. Showers and perhaps isolated thunderstorms are expected with a frontal passage on Wednesday. The tight pressure gradient should lead to breezy conditions. Periods of heavy rainfall will be possible with accumulations of 1 to 2 inches with PW values between 1.25 and 1.5 inches.

Canadian surface high pressure builds into the Southeast U.S.
later next week. Dry and colder weather conditions are anticipated with this airmass, although not quite as cold as this past week.



AVIATION /18Z SATURDAY THROUGH THURSDAY/
High confidence in VFR conditions through the forecast period.

Dry, cool high pressure is in place across the region. Winds are expected to generally be between 4 and 10 knots through today and potentially tonight. Only big issue could be a 20-30 knot west-southwesterly low-level jet expected to develop overnight tonight, which is likely to keep surface winds up just a bit through the night. This should mix down by mid-morning tomorrow, with winds around 10 knots expected by that point. High clouds are expected to begin streaming into the forecast area tomorrow, remaining VFR given the very dry air in place.

EXTENDED AVIATION OUTLOOK...The chance of widespread restrictions increases early next week as moisture returns to the forecast area.
