North American Weather (U.S.A & Canada)

U.S. Reeling From Violent Tornadoes, Epic Flooding, Winter Weather, and Weird Heat

Quote

Wild weather continued to plaster the nation’s midsection on Monday as a multi-barreled storm system shifted eastward. Thankfully, the severe weather threat has ramped down somewhat, with the highest risks now shifting to river and flash floods--from eastern Oklahoma to the Appalachians--and snow and ice, from Nebraska to New England. More than 40 weather-related deaths have been reported since Wednesday. The storminess is related to a gradual realignment of the large-scale pattern over North America, as described in detail by wunderblogger Steve Gregory in his Monday afternoon post. A stunningly warm, moist air mass across the eastern and southern U.S.--by some measures the most tropical on record for early winter--is in the process of being displaced by a strong upper-level storm moving into the central states, bringing much more seasonable cold.

Historic Mississippi River Flood Brings Highest Crest on Record Below St. Louis

Quote

A historic and unseasonable flood has brought the highest flood levels ever recorded to the Mississippi River south of St. Louis, thanks to more than 10 inches of rain that fell over a three-day period that began Christmas Day. At least 25 deaths in Illinois and Missouri are being blamed on the flooding. The Mississippi River crested at its third highest water level on record in St.Louis on January 1. On January 2, the southward-propagating crest brought the second highest flood on record to Chester and the highest flood on record to Cape Girardeau and Thebes. On Monday, January 4, the crest is expected to be about 200 miles south of St. Louis at Caruthersville, Missouri, bringing the third highest flood ever observed there. The latest flood forecasts for the Mississippi River issued Sunday evening by NWS River Forecast Center predicted no other locations would see an all-time record crest, with crests between the 2nd and 10th highest on record expected along most of the Lower Mississippi and the lower portions of two main tributaries, the Ohio and Arkansas Rivers.

Looks like Parts of New York, Buffalo, the Great Lakes, Oswego etc could be in the firing line for some proper Lake Effect Snow in the next 7-10 days..

 

THE PATTERN BECOMES FAR MORE INTERESTING EARLY NEXT WEEK. THE LONG
ADVERTISED PATTERN CHANGE WILL BE TAKING SHAPE ACROSS NORTH
AMERICA...WITH A STRONG WEST COAST RIDGE ALLOWING AN IMPRESSIVE
LONGWAVE TROUGH TO CARVE OUT ACROSS THE EASTERN HALF OF NORTH
AMERICA. THE MEAN PATTERN FOR ALL OF NEXT WEEK WILL FEATURE A DEEP
TROUGH CENTERED IN THE VICINITY OF HUDSON BAY...WITH NUMEROUS HIGH
AMPLITUDE CLIPPER SHORTWAVES MOVING THROUGH THE LONGWAVE TROUGH.
PAST CLIMATOLOGY RESEARCH AND EXPERIENCE SUGGESTS THIS PATTERN CAN
BE VERY ACTIVE FOR HEAVY LAKE EFFECT SNOW IN OUR REGION...AND THIS
APPEARS TO BE THE CASE WITH THIS PATTERN AS WELL.


DEEP COLD AIR SPREADING ACROSS THE GREAT LAKES WILL ALLOW FOR A
STRONG AND DEEP LAKE RESPONSE AT TIMES...WITH THE NUMEROUS MID LEVEL
WAVES PROVIDING LARGE SCALE ASCENT AND DEEPER MOISTURE. THESE WAVES
WILL ALSO BRING CHANGES TO BOUNDARY LAYER FLOW DIRECTION...
SUGGESTING MIGRATING BANDS OF LAKE EFFECT SNOW. OBVIOUSLY AT THIS
TIME RANGE THE DETAILS ARE VERY UNCERTAIN...BUT THE LARGE SCALE
PATTERN CERTAINLY SUGGESTS THE POTENTIAL FOR LONG LASTING...
SIGNIFICANT...HIGH IMPACT LAKE EFFECT SNOW EAST OF LAKES ERIE AND
ONTARIO THROUGH MUCH OF NEXT WEEK. STAY TUNED.

 

 

Talk of some places adding 3-5" PER DAY for the next week or so from the weekend....staggering really! 

 

 

A pretty active pattern in general coming up over much of North America....

Crazy Hot December: USA Edition

This December was crazy hot. And not just in England; it was in the eastern U.S. too.


The National Center for Environmental Information has released the December figures, and they’re staggering. Of the 48 states in the conterminous U.S., only 10 had near-average temperature, 3 were above average, 6 were much above average. A whopping 29 out of 48 were the hottest on record.

Evening all :)

I thought I would add a more personal take on the weather in one part of North America as Mrs Stodge and I have just returned from spending Christmas and New Year in Las Vegas and Rancho Mirage (near Palm Springs) respectively. It's fair to say all the main focus of the weather in North America was points east of us but Nevada and Southern California, unlike much of the populated northern hemisphere, had below average temperatures through the Christmas/New Year period.

December 20th - 28th: Las Vegas, Nevada

We arrived into Vegas on a cool, clear evening on the 20th but the following day, cloud had developed and the next two days were dry but uninspiring. This cloud was the precursor of the storm system which would develop over New Mexico and Colorado. The trough dug down into the US as far south as those states but to the west, a NW'ly flow developed as an HP built in from the Pacific. This drew cool but clear air from the Rockies south.

On the 23rd and Christmas Eve, Vegas was fine and clear and afternoon temperatures reached 16c in the strong sunshine but the evenings soon became cool and then cold. Late Christmas Eve, a new cold front pushed through from the north west introducing colder air. I saw a shower over the mountains to the west of Vegas but there was no precipitation on the Strip. Christmas Day dawned clear and cold and temperatures struggled to 9c and fell below freezing even on the Strip (and much colder out in the Valley and to altitude).

The same weather prevailed through to Monday morning when we drove to Rancho Mirage (about 270 miles on the Interstate).

December 28th - January 3rd, Rancho Mirage, California

We initially left under clear skies but as we headed toward Los Angeles, we saw cloud encroaching from the Pacific which was a weak storm system moving south down the coast. Near San Bernadino, we ran into a shower and an exterior temperature of 5c at 4000 ft. The rain continued as we curved back east but petered out as we approached the Coachella Valley and Rancho Mirage as the temperature rose.

The next five days can be summed up in one word - glorious. Cloudless skies from dawn to dusk allowed for al fresco breakfast and afternoons by the pool. After a cold start, temperatures recovered quickly to reach a seasonal 18c on New Years Eve and New Years Day. As the HP moved across from the Pacific, the wind dropped out and the humidity levels were around 30%. On the 2nd, the first manifestations of a major weather change came into view as high cloud encroached from the west and the wind picked up.

January 3rd - 6th, Las Vegas, Nevada

So, back for a final three days off the Strip but with the weather playing a hand. We drove back under cloudy skies but on Monday afternoon, the storm which drenched the California coast reached Vegas with heavy rain. Not pleasant to drive in but I'm a bit more used to it than some Americans. Tuesday and Wednesday were quieter with sunshine and showers but the media was full of the pattern change and the rain heading for California and the impact it might have on the disastrous long-term drought.

After a foot in some parts over the last few days, Buffalo and parts of Upstate New York look in the firing line for another round of LES snow in the next 48 hours.

I'm due to land in New York on Friday at 6pm EST. Think I'll get there before it hits? Looks a bit marginal to me! 

NYC is shown to miss the worst at this stage worth keeping an eye on though

Too soon to say but at the moment it looks like that would be just about the time snow would be reaching NYC, it probably wouldn't cause any issues there at that time, but it all depends on the timing. NY looks like it won't be getting the biggest totals from this but could still see about 10 inches by the time it's over. Could be marginal though.

Yes, it's looking highly likely that parts of the NE - from Washington up to Boston and NYC could see anywhere from 6" to 2 feet from this storm in extreme cases. A fascinating watch/read coming up. Much more interesting than anything this country will ever have to offer.

18Z GFS has the bullseye close to Washington DC. Were it to verify, it could surpass the 1922 Knickerbocker storm record of 28 inches.
 The jackpot on this run is an amazing 43 inches, somewhere south of DC.

Just watched weather channel over here in washington dc, still lots of uncertainty about the storm.... Focused on the  euro model keeping storm further south whilst gfs sticking to storm slightly further north affecting I 95 corridor more seriously.... Still saying there is much uncertainty with areas affected and amounts, but saying there is possibility this could be a monster storm.... 

Ps should be fast flight home with the jet too.....
