DISCUSSION
COOLER TEMPERATURES WITH BREEZY NORTH WINDS AND A DRIER AIR MASS
WILL PREVAIL BEHIND A COLD FRONT WHICH PASSED THROUGH WESTERN NV
EARLIER TODAY. THE TIGHTEST PRESSURE GRADIENT IS EXPECTED TO MOVE
ACROSS MINERAL/SOUTHERN LYON/SOUTHEAST MONO COUNTIES THROUGH MID-
AFTERNOON WHERE WIND GUSTS COULD REACH 45 MPH AT TIMES, ESPECIALLY
IN NORTH/SOUTH ORIENTED VALLEYS WHERE MORE EFFICIENT CHANNELING OF
THE WINDS CAN OCCUR. ELSEWHERE ACROSS WESTERN NV, WIND GUSTS OF
25-35 MPH ARE EXPECTED WITH LOCALLY HIGHER GUSTS TO 40 MPH FOR THE
BASIN AND RANGE. HIGHER ELEVATION WINDS WILL ALSO INCREASE
ESPECIALLY FOR MONO/MINERAL COUNTIES, WITH PEAK RIDGE GUSTS OF
45-60 MPH. A FEW PATCHES OF BLOWING DUST MAY BE LOFTED FROM
DESERTS AND SINKS OF NORTHWEST-WEST CENTRAL NV, WHILE CHOPPY
CONDITIONS CONTINUE ON PYRAMID LAKE. WHILE MUCH OF THE LATEST
HIGH-RESOLUTION GUIDANCE PRODUCES SOME BUILDUPS WITH ISOLATED
SHOWERS ALONG THE SIERRA CREST IN MONO COUNTY THIS AFTERNOON, THE
NORTH FLOW IS MORE LIKELY TO PUSH THIS SHOWER ACTIVITY WEST OF THE
CREST BY MID-LATE AFTERNOON.
A SECONDARY SHORTWAVE DROPPING SOUTHWARD ACROSS CENTRAL-EASTERN NV
TONIGHT WILL BRING ANOTHER ROUND OF BREEZY NORTH WINDS MAINLY TO
WEST CENTRAL NV OVERNIGHT THROUGH FRIDAY. GUST SPEEDS WILL BE A
LITTLE LESS COMPARED TO TODAY, BUT SOME SITES NEAR AND EAST OF
US-95 COULD AGAIN SEE GUSTS 35-40 MPH. THE PRESSURE GRADIENTS ARE
EXPECTED TO RELAX ACROSS AREAS NORTH OF US-50 BY MIDDAY AND SOUTH
OF US-50 BY MID-LATE AFTERNOON FRIDAY, RESULTING IN DIMINISHING
WINDS AFTER THOSE TIMES. A REINFORCING SHOT OF COOLER AIR WILL
ACCOMPANY THESE NORTH WINDS, WITH HIGHS ONLY NEAR 60 DEGREES FOR
LOWER ELEVATIONS AND 50-55 FOR SIERRA COMMUNITIES.
THE EASTER WEEKEND WILL SEE A DECENT WARMUP DURING THE DAYTIME
WITH HIGHS RETURNING TO THE MID 70S FOR MOST LOWER ELEVATIONS AND
LOWER-MID 60S NEAR THE SIERRA AND OR BORDER BY SUNDAY. MORNINGS
WILL REMAIN COOL THOUGH IN THE DRY AIR MASS, WITH LOWS AROUND
SUNRISE MAINLY IN THE 30S TO LOWER 40S. MAINLY ZEPHYR-TYPE PM
BREEZES ARE EXPECTED EACH DAY, WITH A BIT MORE WIND PROJECTED FOR
SUNDAY AS A WEAK DRY SHORTWAVE BRUSHES ACROSS NORTHERN NV.
SIMILAR CONDITIONS ARE EXPECTED FOR EARLY-MID NEXT WEEK, WITH
FLAT RIDGING OVER CA-NV AND WEAK SHORTWAVE PASSAGES BRUSHING BY
TO THE NORTH. WHILE MOST OF THE REGION REMAINS DRY, LOW-END
SHOWER CHANCES (LESS THAN 15%) COULD REACH FAR NORTHEAST
CA/NORTHWEST NV NEXT TUESDAY-WEDNESDAY, BUT SIGNIFICANT WEATHER
IMPACTS ARE UNLIKELY. THERE ARE SOME SIGNALS IN MEDIUM RANGE
GUIDANCE LEANING TOWARD GRADUAL COOLING AND INCREASED SHOWER
CHANCES LATER NEXT WEEK. MJD
AVIATION
VFR CONDITIONS PREVAIL ACROSS THE REGION THROUGH THIS WEEKEND.

NORTHWEST AT KMMH) THROUGH THIS EVENING WITH GUSTS 20-25 KT, AND
BELOW 20 KT FOR THE TAHOE AREA TERMINALS. WINDS SHIFT MORE TO THE
NORTHEAST ON FRIDAY (EXCEPT NW-N AT KMMH) WITH GUSTS MAINLY 15-20
KT.
FOR THIS WEEKEND, LIGHTER WINDS ARE EXPECTED FOR THE MAIN
TERMINALS, EXCEPT FOR LATE DAY WEST BREEZES WITH GUSTS 15-20 KT
SATURDAY AND UP TO 25 KT SUNDAY. MJD
