February 18-20 Potential Winter Storm
By Andrew at 5:18 PM

There is potential for a winter storm to strike the Midwest and Plains from February 18th to 20th.

The GFS model has been forecasting a fairly strong storm hitting the Midwest for a few days now, off and on again every few runs. The track has varied from run to run, but more times than not it has had the storm go into the Midwest. And when it does go into the Midwest, more times than not it takes the track shown above. As is my favorite guideline to abide by when tracking storms, always look for the trends and not the individual runs. I post this individual run because it sums up what the GFS has been showing for multiple days now.

Even more significant is that the ECMWF model (top) and their prestigious ensemble system (bottom) have joined in the fun. The ECMWF does have the key difference of two low pressure systems in the Great Lakes during this time, while the GFS only has one. The presence of two storm systems would aid in warm air advection and cut down on snowfall for cities like Chicago and northern Indiana, who are slated to get snow from this system per the above GFS forecast. The ECMWF Ensemble system has a single low pressure system, but it is in southern Lake Michigan. This would still support an all snow solution for the aforementioned city and region, but the heaviest snow would certainly be north in northern Wisconsin into Michigan. I do want to watch that area in east Arkansas and to the northeast where the pressure contour lines jut out further south towards the Gulf Coast. That can either mean another low pressure system or the more-likely cold front.

Confidence in a fairly strong storm system hitting the region shown by the GFS: 15% confidence

My favorite blogger is back on :).Anyway Our chances of snow go up come Saturday night into Sunday.(Still not liking that as I have something to do.).The temps will be their so I'm thinking cold(temps in 30's) plus big coastal storm equals the fact that D.C could see our first major snow storm in a long while...Depends on the track though.

Eric Holthaus‏@EricHolthaus

Overnight model trends show the wknd storm ramping up only when it's safely out at sea. We'll have to wait a couple days to get better info.

Eric Holthaus‏@EricHolthaus

To sum up: NYC will likely get 2-4" snow on Wed night, and some potential for a bit more than that over the weekend.

THE PATTERN IS AN ACTIVE ONE FOR THE CONTIGUOUS UNITED STATES THIS
PERIOD, WITH ENERGY TRAVERSING THE NATION COAST TO COAST. THIS IS
PEAK CLIMATOLOGY FOR WINTER STORMS OVER THE EASTERN STATES, SO ANY
PHASING OF THE SPLIT FLOW COULD RESULT IN A HIGHLY IMPACTFUL
CYCLONE FOR THAT REGION. THERE ARE TWO SYSTEMS FATED ON PHASING
THAT MAY PROVE TO HAVE SUCH IMPACT. THE FIRST WILL BE COMPLEX
CYCLOGENESIS JUST OFF THE EAST COAST DAY 4. THE 00Z/12 GEM GLOBAL
PHASES ENERGY MORE QUICKLY AND AGGRESSIVELY THAN THE OTHER MODELS,
WITH THE 00Z/12 GEFS MEAN IMPRESSIVELY DEVELOPED AS WELL. THE
00Z/12 ECENS MEAN INDICATES MODEST PHASING JUST OFFSHORE, SLIGHTLY
MORE DEVELOPED THAN EITHER THE 00Z/12 DETERMINISTIC ECMWF OR THE
00Z/12 DETERMINISTIC GFS. CHOSE THE MIDDLE GROUND OF THE SKILLFUL
ECENS MEAN FOR THE HANDLING OF THIS SYSTEM--THE BAGGINESS IN ITS
SURFACE PRESSURES OFFSHORE ALLOWING WIGGLE ROOM FOR FURTHER
TRENDING. THE SECOND SYSTEM OF INTEREST IS EXPECTED TO COALESCE
OVER THE GREAT PLAINS LATE DAY 6 INTO DAY 7. THIS SYSTEM MAY BE OF
SUFFICIENT AMPLITUDE TO VIGOROUSLY TAP THE GULF OF MEXICO, WITH
IMPORT FOR BOTH CONVECTIVE POTENTIAL AS WELL AS MOISTURE TRANSPORT
INTO THE PRIMARY SURFACE LOW FARTHER NORTH. THE LION'S SHARE OF
ENERGY FEEDING THIS SYSTEM WILL BE DROPPING INTO THE FAR WEST MID
PERIOD IN THE MANNER OF MOST OF THE SHORTWAVES AT THE MEDIUM RANGE
OVER THAT REGION. THESE "INSIDE SLIDERS" PRECLUDE SIGNIFICANT
IMPORT OF PACIFIC MOISTURE BY THE NATURE OF THEIR TRAJECTORIES. AS
WITH THE EAST COAST SYSTEM EARLIER IN THE FORECAST, THE ECENS MEAN
APPEARS TO REPRESENT A MIDDLE ROAD AND IS THE MOST COHERENT OF THE
RECENT GUIDANCE WITH REGARD TO THE TEMPORAL PROGRESSION OF THE
FLOW.
