DISCUSSION

KEY MESSAGE 1: Above seasonal temperatures and dry conditions will prevail throughout the week. A cold front will bring cooler temperatures this weekend.

Now that the front has moved through and the remnants of Isaias are now out of our hair, drier and warmer conditions will move into the area. High pressure will build over the central US through the early half of the week and slowly build eastward by the end of the week. This will lead to dry conditions through the work week and the only concern will be for near record highs given the strength of the upper ridge. Temperatures by the end of the week will be in the upper 80s to maybe even 90 degrees across some interior areas. This will certainly flirt with some record highs as we go through the week. By the weekend, our next system will swing through as the upper trough breaks down and a cold front moves through the area bringing significantly cooler conditions to the area.

AVIATION /00Z MONDAY THROUGH FRIDAY/

12/00z TAFs: KCHS/KJZI/KSAV: VFR through 13/00z. Extended Aviation Outlook: There are no concerns.

MARINE

The Small Craft Advisory for Charleston Harbor has been extended until 8 PM.

Tonight: Breezy west-southwesterly flow at 15 to 20 kts with gusts up to 25 to 30 kts will continue throughout the afternoon and evening as the remnants of Post-Tropical Cyclone Isaias pass well to the west of the region. Therefore, Small Craft Advisories remain in effect from the for the nearshore waters and outer Georgia waters for the majority of the day. Also, west-southwesterly swell will briefly surge into the local waters in the early morning and seas will range from 4 to 7 ft across the South Carolina waters and 4 to 6 ft in the Georgia waters. Thereafter, the swell will slowly taper back and seas will decrease to 3 to 5 ft overnight.

Monday into Thursday: High pressure will build in from behind the passage of the cold front and will be the dominant forecast feature over the next several days. Expect wind speeds to remain relatively breezy on Monday morning, before tapering off through the afternoon and remaining around 5 to 10 kts for the rest of the forecast period. Seas will range from 2 to 3 ft.
