WEATHER PATTERN OVERVIEW: BREEZY CONDITIONS THIS AFTERNOON, WITH
GUSTS TO 25-35 MPH (STRONGEST WINDS IN EASTERN NEVADA). ELEVATED
FIRE WEATHER CONDITIONS DURING THE DAY AS DRY CONDITIONS WILL LEAVE
HUMIDITY BELOW 15%, HOWEVER REMAIN BORDERLINE AS WHEN THE WINDS
INCREASE, HUMIDITY ALSO RISES ABOVE 20% DUE TO THE MUCH COOLER
TEMPERATURES MOVING IN. HIGHS WILL BE SEVERAL DEGREES BELOW NORMAL
FOR NORTHERN NEVADA IN THE 70S WITH CENTRAL NEVADA STAYING IN THE
80S. OVERNIGHT LOWS WILL BE COLDEST IN NORTHERN NEVADA IN THE 30S
WITH SOME AREAS DROPPING TO FREEZING LEVEL, WHILE CENTRAL NEVADA
COOLS INTO THE 40S.
MONDAY, WINDS ARE EXPECTED TO BE LIGHT AND FAIR AS THE MAIN
FRONTAL PASSAGE MOVES NORTHEAST ALONG WITH THE JET STREAK. A
WEAK SHORTWAVE TROUGH PATTERN WILL REMAIN OVER THE NORTHWESTERN
CONUS BEHIND THE LOW PRESSURE SYSTEM WHICH WILL KEEP A NEAR ZONAL
TO ALMOST NORTHWESTERLY FLOW OVER NEVADA. THIS WILL KEEP
TEMPERATURES COOLER ACROSS CENTRAL AND NORTHERN NEVADA WITH HIGHS
IN THE 60S TO 70S. OVERNIGHT LOWS WILL ALSO REMAIN COOL WITH
NORTHERN NEVADA AGAIN IN THE 30S (SOME AREAS REACHING TO FREEZING
TEMPERATURES) AND CENTRAL NEVADA IN THE 40S.
TUESDAY AND THROUGH THE WEEK, THERE IS SOME INCONSISTENCIES
WITHIN THE FORECAST AS TO WHAT TRANSPIRES WITH THE UPPER LEVEL
TROUGH, WITH SOME MODELS SHOWING THE TROUGH STRENGTHENING TO A LOW
PRESSURE SYSTEM AND MOVING OVER NEVADA, WHILE OTHERS SHOW THE
TROUGH REMAINING UNCHANGED. THE MAIN CONSISTENCY IS THAT
TEMPERATURES WILL GRADUALLY WARM BACK TO NEAR NORMAL THROUGHOUT
THE WEEK WITH HIGHS STAYING IN THE UPPER 70S TO 80S UNTIL REACHING
ABOVE NORMAL BY NEXT WEEKEND. WINDS WILL ALSO BE CONSISTENT
STAYING LIGHT TO SOME MILD AFTERNOON BREEZES. NO WEATHER IS
FORECASTED THROUGHOUT THE WEEK.
FORECAST CONFIDENCE & DEVIATIONS: HIGH CONFIDENCE REGARDING COOLER
TEMPERATURES TODAY AND MONDAY. MODERATE CONFIDENCE TO GRADUAL
WARMING TEMPERATURES REACHING TO NEAR NORMAL CONDITIONS NEXT WEEK.
