Gusty Winds Thursday will give way to a great Fishing Opener Saturday and Sunday….Breezy weather to return Monday and Tuesday before a nice warm Cinco De Mayo…Cooler Breezy WX follows Thursday and Friday…..

Its a cooler day today as a rather large but benign upper trof pushes through the region.  High temps are running some 5 to 7 degrees cooler today than Wednesday with highs in the upper 40s.  A few gusts to 55mph around noon today were noteworthy.  This fast moving trof will pass off into the Rockies tonight with a fair weather ridge upon us Friday. Expect a jump of 8 to 10 degrees of warmth tomorrow.  Another weak system will bring a little north breeze Friday, then light west breezes 5 to 15mph are expected Saturday for the Fishing Opener, and Sunday morning with afternoon west gusts to 25 mph possible both days.  Expect high temps this weekend in the upper 50s in Mammoth with mid 60s in the Crowley Lake area.  Lows this weekend will be in the upper 20s at lake level at dawn.

Next week shows another trof affecting our area with breezy weather returning. However, strong gusts like today are not expected for early next week.  Expect a nice warm Cinco De Mayo…Then get ready for the possibility of another wind machine Thursday  May 6th with wave clouds and breezy into Friday the 7th.  Hoping for a nice following Sunday for Mom!  🙂

Adios…

A Wind Advisotry has been Hoisted by the NWS beginning at 8:00PM Tonight through 5:00AM Thursday AM.

A Winter Storm Warning has been Hoisted; Beginning 5:00AM Thursday through 11:00AM Friday for strong winds….Blizzard conditions and heavy snowfall.

NWS Comments;    “Heavy snow expected. Total snow accumulations of 6 to 12 inches near Highway 395, with 1 to 2 feet west of US-395 above 7000 feet. Winds gusting to 55 mph with Sierra Ridge gusts above 80 mph.”

The weekend will be fair with a warming trend into Monday.

The pattern forced by La Nina often changes in the spring as the deep stubborn cold trof in the mean over the eastern part of the country weakens and the pattern becomes more progressive. This process weakens the blocking system in the west. Thus storms can now favor the west for a time, before the cold seasons ends and the cold air from the GOA runs out. That is why after a long dry winter, Spring’s often times will come back wet for a time.

The weather forecast calls for a very breezy Tuesday morning with some snow showers and an inch or two of snow possible on Mammoth Mt.  A more signifacant snow producer is forecasted for Thursday and Friday with solid moderate amounts of snowfall expected.  15 to 20 inches possible over the upper elevations by Friday evening, between 6 to 12 inches in town. The weekend looks fair, so come on up and make some turns!

Another storm, around the end of the month will slow down a bit, so we’ll have a better look at its timing, later next week.

Clear Cold Morning in Mammoth with Single Digit Lows…..Milder Weather on the way this week with more snowfall…..

Yesterday’s wind storm brought gusts over 60 MPH in town.  Mammoth Mt reported 5 to 6 inches at the Main Lodge. The Dweebs figured some 8 to 9 inches fell on the upper mountain.  Today…winter type skiing and boarding returns. Highs today will be in the 20s on Mammoth Mtn.

The cold upper trough over the west will go through some morphing with it becoming more west-east oriented. The upper jet will lift north and be situated near Tahoe this week until Saturday when a final short wave moves through bringing enhanced chances for more snowfall. In the meantime, the pacific opens up, and with cold air in place, mainly warm air advection snowfall will occur with higher snowlevels; beginning late wednesday night and into Thursday. Although it will be breezy, the Dweebs do not expect the strength of winds that occured yesterday Monday, the remainder of the week .  Friday may or may not be dry. This type of pattern is a bit tricky as far as precipitation, as that although we are south of the jet axis, with live in an area that highlights orographicical type precipitation when the flow is moist and the its direction is westerly.  So even though Friday is expected to be dry, it may not be.

The last in this series of systems will come through Saturday AM.  It appears at this time to have plenty of lift. So a period of heavier snowfall is possible Satuday AM before it moves out, later that day.   At the moment, the QPF from CRFC is .63 for Yosemite between Wednesday night and Saturday.  That would suggest simular amounts as just received from yesterday’s storm.  A big Caveat is that models do not do well with warm air advective type systems in areas with orographics from distance timewise. So, we may end up with more snowfall than what is touted at this time for the Thursday through Saturday Storm.  Easter Sunday looks dry and warmer at this time with the warmer weather into early that following week.

The longer range outlook suggest more snowfall into the end of Aprial with periodic storminess through months end.
