DISCUSSION
GUSTY WINDS ARE EXPECTED TO CONTINUE THROUGH 2AM THIS MORNING
ALONG THE MOJAVE DESERT SLOPES AND AT THE SAN LUIS RESERVOIR
BEFORE CALMING ONCE AGAIN LATER INTO TOMORROW MORNING. BUT
STRONG WINDS ARE EXPECTED TO RETURN FOR MUCH OF THE REGION BY
FRIDAY INTO THE WEEKEND, ESPECIALLY FOR THE MOJAVE SLOPES AND
THE LAKE ISABELLA AREAS. THIS IS DUE TO THE DOWNSTREAM AFFECTS
OF A TROUGH MOVING THROUGH THE NORTHWESTERN CONUS, CAUSING
INCREASED PRESSURE GRADIENTS ALOFT THROUGH THE WEEKEND. THIS AIR
IS LIKELY TO ALSO BE DRY AS IT COMES OUT OF THE CONTINENT,
LEADING TO VERY LOW RHS FOR MUCH OF THE REGION, NOT JUST THE
DESERT. THIS COMBINED WITH THE STRONG WINDS WILL LEAD TO
INCREASED FIRE RISK, ESPECIALLY FOR THE WESTERN PORTION OF THE
SAN JOAQUIN VALLEY. FUELS IN THIS REGION HAVE ALSO BEEN STEADILY
DRYING THROUGHOUT THE MONTH.
AFTER THIS TROUGH MOVES EAST, RIDGING IS LIKELY TO BUILD IN BY
EARLY NEXT WEEK, LEADING TO ANOTHER WARM UP BY NEXT WEDNESDAY.
AND EVEN THOUGH THE WINDS ARE EXPECTED TO CALM DURING THAT TIME,
RHS ARE EXPECTED TO DROP A FEW MORE PERCENTAGE POINTS BEGINNING
ON MONDAY AND CONTINUING INTO MID-WEEK, WITH THE VALLEY LIKELY
SEEING VALUES OF 10-15% AND THE MOJAVE SEEING VALUES IN THE
SINGLE DIGITS. THIS COMBINED WITH THE HOT TEMPERATURES WILL
CONTINUE TO KEEP THE FIRE RISK ELEVATED FOR MUCH OF THE VALLEY
AND THE DESERT. DURING THIS TIME, RIVERS AND STREAMS CONTINUE TO
RUN COLD, SO CONTINUE TO PRACTICE WATER SAFETY WHEN USING THOSE
RECREATIONAL AREAS.
