SIERRA LAKE TAHOE FORECAST DISCUSSION (2:30 AM PDT): HIGH PRESSURE ALOFT WILL BRING WARM WEATHER WITH HIGH TEMPERATURES PEAKING AT 5 TO 10 DEGREES ABOVE AVERAGE BY FRIDAY. THERMAL TROUGH  WILL STRUGGLE TO MAKE IT EAST OF THE SIERRA CREST TODAY. THIS WILL MAINTAIN ONE MORE DAY OF LIGHT EASTERLY SURFACE WINDS. THE THERMAL TROUGH WILL FINALLY MOVE EAST INTO THE GREAT BASIN BY FRIDAY FOR A RETURN OF AFTERNOON WESTERLIES. SHOULD SEE WIND GUSTS TO 20-25 MPH ALONG THE SIERRA AND IN THE WRN NV VALLEYS. UPPER RIDGE ISPUSHED EAST ON SATURDAY AS ANOTHER PACIFIC TROUGH MOVES INTO THE WEST COAST. THIS WILL INITIATE A COOLING TREND THAT WILL CONTINUE WELL INTO NEXT WEEK. INCREASING SOUTHWEST FLOW ALOFT IN COMBINATION WITH FAVORABLE GRADIENTS WILL BRING GUSTY WINDS TO 30 MPH OR MORE DURING THE AFTERNOON AND EVENING. 00Z NAM/GFS BOTH SHOW WIDESPREAD 30 AGL WINDS NEAR 25 KTS BY MID AFTERNOON WITH SURFACE RELATIVE HUMIDITY IN THE SINGLE DIGITS TO LOW TEENS. THIS COULD LEAD TO CRITICAL FIRE WEATHER CONDITIONS. SEE FIRE WEATHER SECTION BELOW FOR MORE DETAILS.

SUNDAY THROUGH WEDNESDAY: TROUGH ASSOCIATED WITH UPPER LOW OVER BRITISH COLUMBIA WILL SKIM NORTHERN NEVADA SUNDAY AND DRIVE A FRONT ACROSS THE AREA. 00Z MODELS HAVE BACKED OFF A BIT ON WINDS FOR SUNDAY AFTERNOON...BUT POSITION OF TROUGH AND UPPER JET REMAINS FAVORABLE FOR GUSTY WINDS ACROSS THE AREA. FOR EARLY NEXT WEEK...MODELS CONTINUE TO SHOW BLOCKING PATTERN OVER NORTH AMERICA. RIDGES OVER THE GULF COAST STATES AND ALONG 150W IN THE CENTRAL PACIFIC...WILL MAINTAIN A TROUGH WEST OF THE ROCKIES THROUGH MOST OF NEXT WEEK. THIS WILL OPEN A NORTH TO SOUTH STORM TRACK...WITH POTENTIAL FOR COLD SYSTEMS FROM ALASKA AND WESTERN CANADA TO REACH THE AREA. 00Z MODELS HAVE MAINTAINED A DEEPENING OF THE WEST COAST TUESDAY AND WEDNESDAY...AS A LOW DROPS OUT OF CANADA. DESPITE SOME RUN TO RUN DIFFERENCES IN THE AMOUNT OF COLD AIR AND TRACK/STRENGTH OF THE LOW MODELS  HAVE BEEN CONSISTENT WITH THE TIMING OF THE FEATURE. INCREASED POPS TUESDAY NIGHT THROUGH WEDNESDAY...AND LOWERED THE HIGH TEMPERATURE FORECAST SEVERAL DEGREES BELOW THE STATISTICAL GUIDANCE FOR THE WARM BIAS IN ANOMALOUSLY COLD SYSTEMS.

FIRE WEATHER...MAIN FIRE WEATHER CONCERN IS GUSTY WINDS AND LOW HUMIDITY THIS WEEKEND. TROUGH TO PASS THROUGH THE PACIFIC NORTHWEST WITH THE UPPER JET OVER SOUTHERN OREGON SATURDAY AND SUNDAY. THIS IS A FAVORABLE PATTERN FOR CRITICAL CONDITIONS WITH WIND GUSTS OF 30 MPH OR MORE AND LOW HUMIDITY. THERE IS UNCERTAINTY ON WHICH DAY WILL HAVE THE STRONGER WINDS. YESTERDAY'S MODEL SOLUTIONS WERE FAVORING SUNDAY WITH A FRONT REACHING NORTHERN NEVADA SUNDAY EVENING. HOWEVER SOME OF THE LATEST RUNS HAVE THE STRONGER WINDS ON SATURDAY AFTERNOON AND SATURDAY NIGHT. HIGHEST POTENTIAL FOR CRITICAL CONDITIONS IS ALONG THE SIERRA FRONT SATURDAY DUE TO INCREASING SURFACE THERMAL AND PRESSURE GRADIENTS...AND ACROSS AREAS SOUTH OF I-80 ON SUNDAY WITH THE JET AND FRONT PASSING THROUGH THE AREA.
