January 22-27th Clippers/Hybrids


Chicago Storm

Recommended Posts

12z euro thru 120...most places are getting half of that on Friday night and the remainder on Sunday's event. 

 

beyond this it looks like something is exploding in the middle of the country but don't have time to wait to see what...around 216 all of MO goes from nothing to 2-3".....also there is 2-3" in Louisianna.

Great post Roger. And for tonight's event, Environment Canada just issued a Special Weather Statement for the Golden Horseshoe for significant lake effect/enhanced snow.

From Environment Canada:

City of Toronto

1:21 PM EST Wednesday 22 January 2014

Special weather statement for

City of Toronto issued

Significant lake enhanced snowfall possible starting tonight.

Current information suggests the development of lake effect snow over Lake Ontario potentially impacting areas around the Golden Horseshoe. It is expected the snow band will develop in the late evening hours and persist into Thursday morning rush hour.

At the moment the exact location is difficult to determine but it is expected to generate local snowfall amounts on the order of 5 to 10 cm with poor visibilities of less than half a kilometre.

If the snow band remains stationary for a long period of time, then 15 cm of snow will be possible and a snow squall warning could be issued.

Motorists should exercise caution when driving around the Golden Horseshoe as hazardous driving conditions could develop due to accumulating snow and poor driving visibilities.

The public is advised to monitor future forecasts and warnings as warnings may be required or extended.

Please monitor the latest forecasts and warnings from Environment Canada at www.weatheroffice.gc.ca.

 

Im kind of bearish for all three events. For tonight, the wind field looks too light and variable to get anything of significance onshore. Maybe a localized inch or two somewhere between Toronto and Cobourg. Maybe.

 

For Friday-Saturday, downsloping is the problem. For Sunday, although the models look pretty good, I'm still think a whiff/graze to the south based on the ul pattern.

For tonight's event, CityNews forecaster Natasha Ramsahai mentioned on Twitter (twitter.com/CityNatasha) a few hours ago the lake effect snow chance for the GTA before Environment Canada issued their special weather statement. I guess the in-house models at CityNews is picking up the meso low over Lake Ontario.

4km NAM suite out of BUF is not showing a thing and usually they're pretty good at sniffing stuff like this out. LES is tricky and we'll have to keep an eye on radar but I'd stay a million miles away from forecasting anything close to Roger Smith's numbers.

Yeah, it's tricky for sure. The Jan 2-3 2013 mesolow which dumped 3" in downtown Toronto and 2" in East York came out of nowhere. And the February 16, 2013 event which gave Toronto 2-5" was also a last minute surprise, though CityNews met Adam Stiles mentioned on the 11 pm newscast on Feb. 15/13 that the station's in-house model was picking up on the mesolow for the next day.

EC going with local 2-4" amounts tonight.

HRRR/RAP keeping the band over the lake for the most part. EC is bullish because of the RGEM, which is more aggressive, although it backed off markedly from its 6z run this morning. After looking over some hires sounding's looks like a potential land breeze/meso-low situation as opposed to a single LES band creeping in from the east. Thinking a trace-1" across some parts of the GTA. Maybe we get surprised.

ILN saying ratios could be as high as 40:1 with tonights snow.

 

 

 

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
420 PM EST WED JAN 22 2014


.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
MODELS ARE IN PRETTY GOOD AGREEMENT WITH THE QUICK MOVING SYSTEM
THAT WILL AFFECT THE FA OVERNIGHT. A DIGGING H5 LOW WORKS INTO THE
LOWER GREAT LAKES TONIGHT PUSHING A SFC LOW AND CDFNT ACROSS THE
REGION. QPF AMOUNTS WITH THIS SYSTEM WILL BE LIGHT...LESS THAN
0.05 INCHES...BUT DUE TO THE VERY COLD TEMPERATURES SNOW RATIOS
WILL BE VERY HIGH. EXPECT ANYWHERE BETWEEN 20-40 TO 1 ON THE

RATIOS. HIGHEST SNOW AMOUNTS ARE EXPECTED TO BE TO 1 TO 3 INCHES
IN THE NRN MIAMI VALLEY...WITH SLIGHTLY LESSER AMOUNTS IN THE
CMH/DAY METRO AREAS. IN SRN OHIO AND SE INDIANA ABOUT AN INCH IS
EXPECTED...WITH LESS THAN AN INCH IN NRN KY.

THE BEST CHC OF SNOW WILL BE AHEAD OF THE FRONT...WHICH WILL SWING
THRU BETWEEN 03-09Z. KEPT THE NR 100 POPS ACROSS THE NRN HALF OF
THE FA...BUT TAPERING TO LIKELY IN NRN KY. THE ACCUMULATING SNOWS
SHOULD BE CUTTING OF FROM W TO E AFTER 06Z.

POST FRONTAL WINDS WILL INCREASE AND WILL COMBINE WITH LOWS IN THE
SINGLE DIGITS...MAYBE BELOW ZERO IN PORTIONS OF WHITEWATER AND NRN
MIAMI VALLEYS...TO PRODUCE WIND CHILLS BELOW -10. SO WILL ISSUE A
WIND CHILL ADVISORY FOR TONIGHT INTO THURSDAY. THE ADVISORY WILL
HAVE 2 SEGMENTS. THE FIRST FOR THE NW COUNTIES WHICH WILL RUN
LONGER AND THE OTHER FOR THE REST OF THE FA. THE SRN SCIOTO VALLEY
MIGHT BE MARGINAL FOR THE VALUES...BUT WILL NOT LEAVE THEM OUT.

Sunday certainly has my eyes, the Friday clipper keeps moving along once it passes by as the parent low stalls out over Hudson's Bay. Friday's clipper won't block the road for Sunday's, it will open it enough that Sunday's clipper could amplify just a touch and move east versus shearing southeast.

You're definitely bullish then, it sounds like.

I wouldn't say bullish but this time there won't be a remnant clipper blocking the path for the next one. Realistically Friday's clipper is a wave that forms on the fast moving Arctic front, that will keep on moving as it blows past the both of us.
