SIERRA LAKE TAHOE FORECAST DISCUSSION (3:08 AM PDT): No significant change to the short term grids. A flat ridge will move overhead today before an upper disturbance over the Eastern Pacific moves overhead Thursday and Thursday night and pushes a cool front through the area. As far as today, westerly winds will kick in this afternoon as a thermal low develops over Central Nevada. With residual moisture and some convergence in the favored Lassen and Mono-Mineral convergence zones (care of the increasing afternoon westerlies), very isolated thunderstorms could develop although thinking the best chance will be for Mono-Mineral Counties. This evening, have left the slight chance of storms across a broad swath of Western and West-Central Nevada as the westerly winds bring brief convergence along the leading edge of the wind push. Not all that confident in storms forming out in the basin east of Reno with the highest chance over Mono and Mineral County where the best convergence over the higher terrain will develop and models bring the most significant relative humidity increase aloft (indicating model convection or cloud development). Thursday, an upper disturbance off the coast will move into the region. This will bring a significant increase in wind over today as a strong pressure gradient develops between extreme Northern Nevada and California an a low pressure center over Eastern Nevada. Precipitation wise, scattered showers and a few possible storms still looks decent over the northern half of the County Warning Area Thursday afternoon and evening as convergence along an advancing front combines with large scale upper lift ahead of the disturbance to provide lift for precipitation/possible storms. Further south, it will be more of a wind issue than a precipitation issue with the strong pressure gradient development by Thursday afternoon. Wind gusts to 35-45 mph are a good bet especially near and south of Highway 50 where a jet streak will move overhead and the maximum progged pressure gradient/heating will exist. Thursday night and Friday morning, the upper low will slide overhead and then into Southeastern Nevada bringing the threat for showers along and to the east of the low track (currently just east of Reno) with residual clouds possibly extending back to the Sierra. Friday will be a good 5 to 10 degrees cooler than Thursday for most areas as weak high pressure settles intot he Western Great Basin.

SATURDAY THROUGH TUESDAY: No major changes to the long term forecast. Upper ridge builds into the West Coast for the weekend, with temperatures rising to 5-10 degrees above normal. Southwest flow aloft will keep conditions dry through at least the weekend. Medium range models do show a trough moving into the Pacific Northwest by Monday. There is low overall confidence on the forecast past Monday, due to significant differences in the model heights/jet placement. The 00Z GFS keeps the ridge in place over the Great Basin, and deflects the trough into the Pacific Northwest. The ECMWF/GEM drop the trough well into the Great Basin by Tuesday. Kept in the slight chance of showers in the North for Monday and Tuesday due to the potential trough/frontal passage, but this may end up changing over the next couple days. We will also have to keep an eye on winds next week, as a frontal passage could bring stronger winds to the region as well.

FIRE WEATHER...HUMIDITY-WISE, RECOVERIES THROUGH TONIGHT WILL BE BETTER THAN WHAT HAS BEEN OBSERVED THE PAST COUPLE NIGHTS BUT STILL NOT GREAT FOR MIDSLOPES ESPECIALLY SOUTH OF HIGHWAY 50. HUMIDITIES WILL BE ON THE RISE THURSDAY ACROSS THE NORTHERN CWA  (ZONES 270/271/278/458) AS PRECIPITATION DEVELOPS NEAR A COOL FRONT WITH UNCERTAINTY IN HOW FAR SOUTH THE HUMIDITY RISES WILL REACH WHEN WINDS KICK UP THURSDAY (WILL HIGHER HUMIDITIES REACH THE SIERRA FRONT?). HOWEVER, OUT IN THE BASIN SOUTH AND EAST OF RENO IT LOOKS TO REMAIN QUITE DRY WITH WIDESPREAD SINGLE DIGIT READING LIKELY THURSDAY AFTERNOON. WIND-WISE, WESTERLY WINDS WILL  INCREASE THIS AFTERNOON WITH GUSTS TO 30 MPH ESPECIALLY IN THE SIERRA/SIERRA FRONT. WINDS WILL STRENGTHEN THURSDAY  AFTERNOON AND EARLY EVENING AS A TROUGH PUSHES INTO THE REGION. WIDESPREAD GUSTS OF 35 TO 45 MPH CAN BE EXPECTED AND THIS  COMBINED WITH THE LOW RELATIVE HUMIDITY IS A CONCERN. WILL HEADLINE THIS IN THE FIRE WEATHER FORECAST AND CONTINUE TO MONITOR  OVER THE NEXT DAY BEFORE MAKING A DECISION ON A POSSIBLE FIRE WEATHER WATCH. AS OF NOW, THE BEST POTENTIAL IS FOR FIRE ZONES 273, 450, 453, AND 459. ALSO OF CONCERN ARE THE SLIGHT CHANCES FOR THUNDERSTORMS IN NEVADA. STORMS WILL BE A HYBRID OF WET AND DRY AND FIRE  STARTS ARE POSSIBLE TODAY. THERE ARE BETTER CHANCES FOR SHOWERS WITH THUNDERSTORMS NORTH OF HIGHWAY 50 ON THURSDAY AS THE TROUGH MOVES INLAND.
