FORECAST 20-JAN-09

Grab your bear can or camp chair, kick your feet up and chew the fat about anything Sierra Nevada related that doesn't quite fit in any of the other forums. Within reason, (and the HST rules and guidelines) this is also an anything goes forum. Tell stories, discuss wilderness issues, music, or whatever else the High Sierra stirs up in your mind.

FORECAST FOR THE OWENS VALLEY, MAMMOTH AND MONO COUNTY
PROVIDED BY DENNIS MATTINSON
EASTERN SIERRA WEATHER FORECASTER
KSRW 92.5 / 96.5 FM AND TV-33

TUESDAY, 20-JAN-09, 7:10

LARGE SCALE, PERSISTENT RIDGE THAT'S BEEN GIVING OUR AREA DRY WEATHER AND ABOVE NORMAL TEMPERATURES IS MOVING EAST INTO THE NORTHERN PLAINS. AT THE SAME TIME, A CLOSED LOW IN THE EASTERN PACIFIC IN MOVING CLOSER TO THE CALIFORNIA COAST. THIS SYSTEM WILL HAVE A SOUTHERLY TRACK, THEREFORE WILL BE PICKING UP SOME SUBTROPICAL MOISTURE. I EXPECT THE SYSTEM TO ARRIVE IN THE SOUTHERN SIERRA AND BEGIN SPREADING NORTHWARD SOMETIME ON WEDNESDAY INTO THURSDAY. SNOW LEVELS WILL REMAIN HIGH, IN THE 8,000 FOOT RANGE. THIS IS NOT A BIG SYSTEM, BUT WE SHOULD SEE SOME 6 INCHES IN THE UPPER ELEVATIONS, BUT NOT MUCH IN THE TOWN OF MAMMOTH. THE OWENS VALLEY SHOULD ALSO SEE SOME RAIN SHOWERS. THE SYSTEM MOVES OUT THURSDAY NIGHT WITH UNSETTLED WEATHER THROUGH THE WEEKEND AS ANOTHER SYSTEM ATTEMPTS TO MAKE LANDFALL ON SATURDAY INTO SUNDAY.

FOR THE OWENS VALLEY:

TODAY: PARTLY TO MOSTLY SUNNY SKIES WITH HIGHS NEAR 58. SOUTHEAST WIND LIGHT.
TONIGHT: MOSTLY CLOUDY SKIES WITH LOWS AROUND 33. SOUTHEAST WIND 3 - 5 MPH.
WEDNESDAY: MOSTLY CLOUDY WITH A 20% CHANCE OF RAIN. HIGHS AROUND 58. SOUTHEAST WIND 6 MPH.
