Marine Weather and Tide Forecast for Manchester, CA

DISCUSSION
Thursday and Friday broad/weak troughing will drift by to our north, but will not have much more effect than mid level cloud cover and cooler temperatures, especially in interior valleys.
The chance of isolated thunder Friday afternoon is becoming less and less likely for eastern Trinity county with minimal moisture available to initiate convection. High amplitude ridging is expected to return Saturday and Sunday, allowing temperatures to briefly rebound into the 70's and 80's. Long range models are becoming more confident in another upper trough and surface frontal system clipping the region late Sunday into Monday. NBM indicates 30 to 40% probabilities for >0.01 inches, most likely Monday morning should it occur. This is forecast to be followed by more warming mid next week.



AVIATION
High pressure will wedge back into Northwest California during this TAF period. This afternoon and into the evening, north to northwesterly winds will pick up at most all area terminals. In southern Mendocino and Lake counties, gusts to 20 knots are likely into this evening. Late this evening and into early Friday, marine stratus is projected to develop under an inversion, mostly around the Humboldt Coast north of Cape Mendocino. There could be southerly reversal winds around the Del Norte Coast which brings the possibility of stratus moving into KCEC. HRRR indicates about a 20 to 30 percent chance for MVFR conditions at KCEC by early Friday morning. MVFR conditions are most likely at KACV by early Friday morning; however there is a 50 to 60 percent chance for IFR ceilings and a 25 to 35 percent chance for LIFR ceilings. KUKI is expected to remain VFR. /JLW



MARINE
Northerly winds will increase again as high pressure builds back over the Pacific throughout today and into Friday. As a result, small craft winds and seas are forecast for the southern waters Friday and Saturday. Another weak system will approach the region over the weekend allowing winds to decrease again and possibly even turn out of the south briefly in the northern waters by Sunday. Northerly winds and steep seas are projected to increase again by the middle of next week as high pressure builds back into the region. /RPA /JLW
