145 PM PST THU FEB 21 2019 [HEAD]

.SYNOPSIS...COOL AND DRY WEATHER CONDITIONS WILL CONTINUE INTO
FRIDAY WITH OUR NEXT CHANCE OF PRECIPITATION RETURNING TO THE NORTH
BAY THIS WEEKEND. RAIN CHANCES SHIFT SLIGHTLY SOUTHWARD EARLY NEXT
WEEK WITH THE POTENTIAL FOR UNSETTLED WEATHER CONTINUING INTO NEXT
WEEKEND. [DISC]

Discussion. As of 01:45pm PST Thursday… precipitation has come to an end across the region this afternoon under partly cloudy sky conditions. Temperatures are generally a few degrees cooler compared to 24 hours along with a much drier air mass. With this and breezy northerly winds, it feels chilly outdoors. The wind speeds are forecast to diminish late in the night and will allow for decent cooling with temperatures dropping into the 30s for most areas, even some of the inland urban centers. Expecting lower 40s in and around San Francisco while the region's coldest locations could fall into the upper 20s on Friday morning. Thus, frost will be possible across much of the region early Friday morning with the potential for black ice on any remaining wet roadways. ∨

COME TO AN END ACROSS THE REGION THIS AFTERNOON UNDER PARTLY
CLOUDY SKY CONDITIONS. TEMPERATURES ARE GENERALLY A FEW DEGREES
COOLER COMPARED TO 24 HOURS ALONG WITH A MUCH DRIER AIR MASS. WITH
THIS AND BREEZY NORTHERLY WINDS, IT FEELS CHILLY OUTDOORS. THE
WIND SPEEDS ARE FORECAST TO DIMINISH LATE IN THE NIGHT AND WILL
ALLOW FOR DECENT COOLING WITH TEMPERATURES DROPPING INTO THE 30S
FOR MOST AREAS, EVEN SOME OF THE INLAND URBAN CENTERS. EXPECTING
LOWER 40S IN AND AROUND SAN FRANCISCO WHILE THE REGION`S COLDEST
LOCATIONS COULD FALL INTO THE UPPER 20S ON FRIDAY MORNING. THUS,
FROST WILL BE POSSIBLE ACROSS MUCH OF THE REGION EARLY FRIDAY
MORNING WITH THE POTENTIAL FOR BLACK ICE ON ANY REMAINING WET
ROADWAYS. [DISC]

Dry and slightly warmer conditions are forecast during the day Friday as a short-wave ridge moves over the region. Temperatures look to warm into the middle/upper 50s for most while 40s linger in the region's higher elevations. Chilly overnight temperatures will continue for the start of the upcoming weekend before they moderate heading into early next week in response to increased low level moisture and cloud cover. Chances for precipitation return to the far northern portions of the North Bay late in the day Saturday and potentially down into the San Francisco Bay Area by Sunday. At this time, the best chances for widespread precipitation during the weekend will be over far Northern California as a weak atmospheric river advects inland across that region. Rainfall will drop off dramatically to the south with locations across the Central Coast staying dry through the entire weekend. ∨

HEADING INTO EARLY NEXT WEEK IN RESPONSE TO INCREASED LOW LEVEL
MOISTURE AND CLOUD COVER. CHANCES FOR PRECIPITATION RETURN TO THE
FAR NORTHERN PORTIONS OF THE NORTH BAY LATE IN THE DAY SATURDAY AND
POTENTIALLY DOWN INTO THE SAN FRANCISCO BAY AREA BY SUNDAY. AT THIS
TIME, THE BEST CHANCES FOR WIDESPREAD PRECIPITATION DURING THE
WEEKEND WILL BE OVER FAR NORTHERN CALIFORNIA AS A WEAK ATMOSPHERIC
RIVER ADVECTS INLAND ACROSS THAT REGION. RAINFALL WILL DROP OFF
DRAMATICALLY TO THE SOUTH WITH LOCATIONS ACROSS THE CENTRAL COAST
STAYING DRY THROUGH THE ENTIRE WEEKEND. [DISC]

More widespread rainfall may drop southward Monday into Tuesday, yet confidence is medium at best as the forecast models and run-to-run solutions are not consistent. At this time, areas north of the Golden Gate appear most likely to see widespread measurable precipitation with amounts of 1–3 inches (likely higher in the coastal ranges) through Tuesday. Meanwhile, precipitation will be generally less than 1 inch for San Francisco and points southward with 0.25" or less for the Monterey Bay region/Central Coast. We will continue to monitor the model output in the coming days and adjust the forecast accordingly. ∨

The models differ even more so heading into the latter half of next week with the ECMWF [European Center for Medium-Range Weather Forecasts model] drying conditions out region-wide late Wednesday into Thursday with the GFS [Global Forecast System: global spectral model used primarily for aviation weather forecasts; provides guidance out to 384 hours at 00, 06, 12 and 18UTC.] simply shifting precipitation back to the north. The longer range guidance suggests the potential for continued unsettled weather heading into the first weekend if not the first full week of March. As a result, the CPC [Climate Prediction Center] has our entire region in a 60% probability of above normal precipitation in their 8–14 day outlook. Stay tuned. ∨
