Today a moisture starved trough approaches the area from the NW. A strong east – west oriented jet will be associated with this trough, so windy conditions will prevail in Mono and Inyo Counties. A High wind warning is in effect later today for Inyo County and a Red Flag Warning for Mono County. Blowing dust is possible along Hwy. 395. Temperatures will cool a bit today and Friday. Another warm-up is on slate over the weekend, as an upper ridge off the Baja coast makes it presence felt. So temps will rebound to a bit above normal by Sunday.
Update: Very good fire danger today with humidity ranging from 8 – 15 % and gusty winds to 40 mph in the Owens Valley.

The see-saw battle between high pressure and low pressure continues. So, Mondays low that caused the windy conditions moved on Tuesday, as high pressure built in behind it. Today, that high pressure, centered over Baja, continues with warm temperatures. On Thursday it gets nudged out of place by another low pressure system passing to our north. Thus cooler temps tomorrow and Friday. Then the weekend sees another warm-up as high pressure once again builds into the area. This will give us above normal temperatures thru the early part of next week.
FOR THE OWENS VALLEY:
Today: Sunny then clear at night. Highs 84 – 94 and lows 58 – 63. Winds NW 10 mph.
Thursday: Mostly sunny then partly cloudy in the evening. Highs 87 – 92 and lows 51 – 56. Winds SW 10 – 20 mph.
FOR THE TOWN OF MAMMOTH LAKES:

That NORCAL low that brought windy conditions yesterday has departed eastward. In its wake an EPAC ridge starts to build in and brings seasonal temps to our district today then a little higher tomorrow. On Thursday, another low moves thru, but this time a bit farther south. It brings a few breezes and slightly lower temperatures thru Friday. By the weekend another ridge builds in bringing warmer temps and dry weather thru the weekend.

Today: Mainly sunny. Highs 80 – 85 and lows 55 – 6o. Winds NW 10 mph.

MONDAY May 14, 2012
Low pressure pushing thru NORCAL today will lower temps slightly and bring on gusty winds in Mono and Inyo Counties. I expect winds in the Owens Valley and Mono County to pickup later this morning to SE 15 – 25 G 40. Low humidity and those winds will increase the fire danger today. That low moves east on Tuesday setting up a building EPAC ridge over the area. Temperatures will thus move back up to above normal by Wednesday.
Update: The Owens Valley saw early gusts to 40 mph and this should continue until past 8 pm this evening.
FOR THE OWENS VALLEY:
Today: Sunny with mostly clear skies in the evening. Highs 85 – 90 and lows 53 – 58. Winds SE 15 – 25 mph G 40.
Tuesday: Mainly sunny with clear skies in the evening. Highs 85 – 90 and lows 56 – 60. Winds N 10 mph.
FOR THE TOWN OF MAMMOTH LAKES:
Today: Mostly sunny then clear in the evening. Highs 65 and lows 39. Winds S 15 – 20 mph G 30.
Tuesday: Mainly sunny with clear skies at night. Highs 65 and lows 40. Winds W 5 – 15 mph.
FOR MONO COUNTY:
Today: Clear. Highs 69 – 79 and lows 31 – 41. Winds SW 15 – 25 mph G 35.

SUNDAY May 13, 2012
Today should be the warmest in the last week or so, as high pressure continues to dominate. However a couple of systems passing to our north this week will moderate temperatures just a wee bit, one on Monday into Tuesday then another Thursday into Friday. These systems will bring a few clouds over the Crest and a slight chance of an isolated shower and thunderstorm over the upper elevations. Along with this, windy conditions will prevail in both counties on Monday.
