The 12z GFS has a good looking High position sitting in southern Quebec.
The 12z also shows moisture stretching all the way back into southern Missouri and northern Arkansas.
The last 3 GFS runs have trended more wintry for Friday. It appears to heading in the general direction of the Euro for a change…
Here is 12z, 6z and 0z for the same Friday time stamp,
The GFS has had some great runs over the last 2 days for the first 2 weeks of February.
I posted the model runs a couple of pages back in this thread showing a series of storms from recent GFS runs that could produce a very wintry first half of February.
Lol, plenty of cold this month.
This doesn’t even mention the number of frigid overnight lows.
It’s a below normal month in the middle of Winter that some people thought is now impossible because of….
The 18z GFS keeps going with more chances towards the end of the run.
Day 16 ends with a cold look with a developing low in the Central states that could take aim at us if the run went out a few more days.
The 18z GFS is lining up the Winter storm chances over the next 16 days.
We should have opportunities to score more snow.
Rest up…many days of tracking are on the way….
This would be a front pushing through with energy left behind that then causes a second wave to develop that brings the frozen precip.
These are difficult to pull off, but we have scored in the past with this type of set up.
Here is the trend on the Canadian from 12z yesterday to 12z today.
Check out difference in the low position.
The trend could be our friend this time for more wintry outcome.
Yes, Thursday pm into Friday has been trending towards a better cold press with a solid wave running along the slowly moving front.
The 12z Canadian & GFS are slowly trending southeast with the cold press and the 12z Euro showed how CTP can win in this set up.
Let’s see how this trends over the next couple of days.
The 6z GEFS has temps below normal for the first half of February with a few Winter storm chances.
Once we get past our quick few day warm up this week, we should be back in the Winter storm chance business.
Here are GEFS temps for week 1 and 2 and then the 10 day snow from day 5 to 15.
The 6z NAM continues to increase snow amounts for the LSV, especially York & Lancaster.
Most west of the river is front the front running preliminary system, but south & east of Harrisburg gets into the western edge of the coastal precip this run.
3z HRRR is continuing to juice up the front running snow tomorrow.
MDT this run has 1.1 inches of snow by 4 pm tomorrow-this is 10-1 ratio, so Kuchera would be even better.
Several more hours of light snow would follow before any possible enhancement from the coastal low.
