UPDATED FCSTS TO INCLUDE SCATTERED THUNDERSTORMS FOR THE REST OF THE DAY OVER HUMBOLDT COUNTY. .AVIATION...VFR CONDITIONS WILL CONTINUE IN MOST AREAS THRU THE MID-AFTERNOON HOURS.

WINDS WILL BE QUITE STRONG TODAY AND THIS EVENING...OUT OF THE SOUTH AT 20 TO 35 MPH WITH GUSTS TO 45 MPH...EXCEPT LOCALLY TO 50 MPH IN ELY...P68...AND TPH.

IF THE FRONT DOES STALL IN THIS AREA...TPH COULD RECEIVE MODERATE TO HEAVY SHOWERS...WITH RAIN CHANGING TO SNOW TONIGHT.

MUCH COOLER TEMPERATURES ARE EXPECTED WEDNESDAY AND THURSDAY ALONG WITH RAIN AND SNOW SHOWERS AS THE STORM SYSTEM MOVES THROUGH THE REGION. THE WEATHER IS EXPECTED TO IMPROVE BY THE END OF THE WEEK. SHORT TERM...TODAY THROUGH THURSDAY. THE RECENT SPELL OF PLEASANT WEATHER WILL COME TO AND END TODAY A STRONG UPPER TROUGH BEGINS TO MOVE INTO THE REGION. THE UPPER TROUGH AN ITS ASSOCIATED COLD FRONT WILL ENTER WESTERN NV BY THIS AFTERNOON. PRECIP WILL BEGIN IN HUMBOLDT COUNTY THIS MORNING...THEN WILL SPREAD EASTWARD THROUGH THE DAY AS THE COLD FRONT ADVANCES EASTWARD.

LI'S FALL TO INTO THE -2C TO -3C RANGE WITH CAPE VALUES SHOWN TO BE BETWEEN 400-800 J/KG...ON TOP OF STEEPENING MID-LEVEL LAPSE RATES. THE LIMITING FACTOR HOWEVER WILL BE THE LACK OF MOISTURE AS PW'S ONLY EXPECTED TO BE AROUND 0.50". DESPITE THIS STILL COULD SEE ISOLATED LOW-TOPPED T-STORMS ESPECIALLY OVER ELKO COUNTY. THE OTHER BIG STORY AHEAD OF THE COLD FRONT WILL BE THE TIGHTENING PRESSURE GRADIENT OVER CENTRAL NV AND H7 WINDS SHOWN TO INCREASE TO 40-50 KNOTS.

SNOW LEVELS WILL COME CRASHING DOWN ALONG AND BEHIND THE COLD FRONT AND WILL PROBABLY DROP TO THE VALLEY FLOORS BEHIND THE FRONT.
