You know it's a torch when brutally cold = normal temps

My whole perception of normal temps is out of whack right now. Highs near 50 sounds cold to me. Also, I notice that I have a 30% chance of rain on Thurs night with a low near 36. Maybe the mountains will get some snow ? Road trip possibly ?

check this out. Monster storm nailing the bering sea/aleutions..minimum pressure expected to get down into the 920 to 925mb range.  currently on adak island west winds at 77mph with gusts to 101..but a couple of hours ago they had a sustained with of 94 gusting to 122! I know storms in the 920s or 930s are not unheard of  but i don't think i've ever heard of winds gusting to 125mph at the surface with them. That seems absolutely incredible when you think about how huge the windfield is and the lesser pressure gradient  compared to a hurricane.

 

This was the local forecast for parts of the islands.

 

Tonight
Rain in the evening...mixing with snow after midnight. No snow accumulation. Lows in the mid 30s. Southwest wind 60 to 80 with gusts to 110 mph.
 
current discussion from anchorage first with the second being the prior discussion. 
 
MEANWHILE THE BIG STORY OF THE DAY IS A VERY DEEP LOW THAT CONTINUES
TO RAPIDLY INTENSIFY NEAR THE WESTERN AND CENTRAL ALEUTIANS. THE
UPPER JET DYNAMICS WITH THIS SYSTEM ARE AS IMPRESSIVE AS CAN BE.
THE LOW DEVELOPED WITHIN A SUBTROPICAL JET COUPLET (LEFT EXIT
REGION OF ONE JET STREAK/RIGHT ENTRANCE REGION OF ANOTHER) AND A
POLAR JET STREAK COMING IN FROM THE WEST HAS NOW MERGED IN WITH
THE SUBTROPICAL JET STREAK TO THE SOUTH OF THE LOW CENTER. THIS IS
ADVECTING DEEP ARCTIC AIR INTO THE SYSTEM HELPING TO DEEPEN IT
EVEN FURTHER. ALTHOUGH THERE ARE NO SURFACE OBSERVATIONS IN THE
IMMEDIATE VICINITY OF THE LOW CENTER THE ESTIMATED CENTRAL
PRESSURE WAS 940 MB OR LOWER AS OF LATE MORNING. CONDITIONS
ACROSS THE ALEUTIANS AND INTO THE BERING SEA ARE RAPIDLY
DETERIORATING. THE PRIMARY THREAT WITH THIS SYSTEM IS HIGH WINDS
AND SEAS. HOWEVER...THE AIR MASS OUT AHEAD OF THE (NOW) OCCLUDING
FRONT IS COLD ENOUGH TO SUPPORT SNOW AS PRECIP FIRST ARRIVES...SO
SOME AREAS WILL SEE A BRIEF PERIOD OF BLOWING SNOW. FOR
SHEMYA...WHICH IS ON THE BACK SIDE OF THE SYSTEM...PRECIP WILL BE
ALL SNOW. TEMPERATURES ARE SITTING A COUPLE DEGREES ABOVE FREEZING
RIGHT NOW...BUT AS WINDS BACK AND TEMPS DROP A BIT THERE COULD BE
A BRIEF PERIOD OF NEAR BLIZZARD CONDITIONS LATER TODAY TO GO ALONG
WITH THE HIGH WINDS.

 

 

2nd

OUT WEST...A POWERFUL CYCLONE IS BEGINNING RAPID INTENSIFICATIONSOUTHWEST OF SHEMYA NEAR 47N. THIS POWERFUL CYCLONE IS FORMING OFFTHE KUROSHIO CURRENT...AND HAS AN IMPRESSIVE ARCTIC FEED OF AIRINTO THE BACKSIDE OF THE LOW...WITH THE POLAR JET DRIVINGIMPRESSIVE UPPER LEVEL DIVERGENCE. THIS SYSTEM HAS ENOUGH LATENTENERGY RELEASE FROM THE MOISTURE OFF THE KUROSHIO CURRENT THAT ITIS FORMING ITS OWN COUPLED UPPER LEVEL JET STREAM. BY LATE THISAFTERNOON...THIS CYCLONE WILL DEVELOP A BENT-BACK FRONTALSTRUCTURE...A CLASSIC SIGNATURE FOR VERY INTENSE CYCLONES...WITHSTORM FORCE TO HURRICANE FORCE WINDS MOVING INTO THE BERING SEAAND ALEUTIAN CHAIN. IN TERMS OF CENTRAL PRESSURE...WITH ANEXPECTED DROP INTO THE 920 HPA RANGE...THIS STORM WILL PUT ITSELFINTO THE TOP ECHELON OF INTENSE CYCLONES TO IMPACT THE BERING SEA.CENTRAL PRESSURES THIS LOW ARE COMMON FOR CATEGORY 3 AND HIGHERHURRICANES...TO GIVE AN IDEA HOW INTENSE THIS BAROCLINIC ANDSYNOPTIC SCALE CYCLONE IS.

This was from 9 hours ago...

Here is an update on the hurricane force low currently moving into the Bering Sea!

The OPC 00Z Pacific surface analysis shows the low has dropped to a pressure of 928 mb. 00Z Himawari visible satellite imagery shows the impressive structure of the storm along with the analyzed location of the low center. Finally, several earlier ASCAT passes over this storm reveal the swath of hurricane force winds (> 64 KT) to the south of the low.

I hope so, this horrific pattern is really getting on my last nerve. [/quot

Agree with that. We live with warm weather for most of the year. Would be nice to not need the AC on Christmas. Everyone who is enjoying it should be boiled in his own pudding and buried with a stake of holly in his heart.
