McHenry area afternoon

Swallow Falls by Derek Buckel

Afternoon update 1:15pm 12/10/19

December 10, 2019

Colder air pushing back in after the mild 24 hours and in some areas 48 hours. The mild rain pretty well wiped out the snow cover that existed in the high ground, except for a few patches here and there. Now the question is, how much returns?

Thoughts have no changed drastically off this doodle map posted from yesterday. One thing to note, a strong leaning to the lower side of the numbers are in play. East of the Alleghenies, still a wild card.

The models

Here is yesterdays 12z ECMWF

• 

Today’s 12z ECMWF

• 

Not a great deal of change in the Euro.

Yesterday 12z GFS

• 

Today’s 12z GFS

• 

more in line with the ECMWF in lowering totals, but likely overdone yet in the immediate area.

Yesterdays 12z Nam vs today’s

• 

• 

showing that area east much better and that area still may be the area the models adjust too later on.

The NWS forecast yesterday

• 

The NWS forecast today

• 

While overall I agree with local totals being lowered and still in the low range of the window on the doodle map, the NWS, mainly Sterling sticks the best accumulation in between where most modeling has it.

Sterlings forecast discussion

Sleeper area in the event still remains the Blue Ridge and north into Pa, east of the Alleghenies.
