Itstrainingtime

It's currently 80 degrees in Bowie, MD and 55 in Annapolis - they are less than 20 miles apart.

Perhaps sometimes in some places, on the whole I don't agree with you. Lots of examples today of locations with much cooler temps than surrounding areas. You can't tell me that all of the instruments are whacked at MDT, Inner Harbor, Annapolis, etc. It's not the instruments, it's the effect of adjacent very chilly waters this time of year.

Oh, I totally understand and agree with you. I think that's why there's so much fuss down south with DCA's snow and temp records...sitting right on the river in that valley no doubt influences their numbers as well.

Breeze coming across the chilly river doing it's thing...

Lancaster officially hit 70 as did the historic district.

Incredible - you don't have to drive far at all right now out of LA proper to get into deep winter. Always love flying into LAX or SNA (John Wayne in Orange County) to enjoy the descent over the last mountain range...the Pacific is right in front of you along with millions and millions of people in the valley between the ocean and the mountains.

There is most definitely a water influence in today's temps - at 2pm, it was 77 at BWI and 61 at the Inner Harbor. Even more impressive...it was 49 at Annapolis at 2pm.

Back to MAG's post and QPF numbers - the GFS and Euro agree that Mammoth CA receives between 8-10" of QPF over the next 7 days...all of course, will be snow. And, they're talking about 20-1 ratios according to the local NWS office. Mammoth Mountain now feels that with the amount of water content in their current snowpack plus what's coming over the next week, they'll be skiing into at least the middle of July if not August. (that would be without any snow after next week which is HIGHLY unlikely.) The current base is 13' at Main and 20' at the summit. I'm sort of excited for my trip. Starting to wonder if we'll have travel issues heading up CA 203 into Mammoth if this keeps up.

Pretty remarkable - 68 currently at home and here at work.

Thank you for responding. Great information and lots of learning with that.

67...keep up.

"We" only got to the upper 50s or low 60s today! LOL

It is up to 66 here now...

Geez, just now approaching 1pm and it's already up to 76 at Dulles.

Yep, temps just took off here so we'll see what the next few hours brings.

That seems realistic - it did spike 4 degrees over the past 30 minutes to 60 here at 12:30pm.

GFS delivers wintry weather later next week via a well-timed trailing wave after an initial low cuts well west on Thursday. This would be a scenario that would probably be our best shot during this time frame.

Sunny and 56 here as well - thought it would be in the 60s at this point if we're going to get well into the 70s.

Are you related to a poster from WV?

Another reason why I don't like snow maps - there are many types of maps available, and it's easy to cherry pick (unknowingly I'm sure at times) a map that either shows a lot of snow or very little. I think all of it creates both confusion and hard feelings. Some maps include sleet, some do not. I think some are based on different ratios than others. And then, there's the positive snow depth maps, which to me at least would seem to be what matters most...when the storm ends, just how much snow is going to be on the ground... Here is the 6z GFS positive snow depth map - copy paste from our neighbors to our south so it only includes the southern tier (sorry folks north of the turnpike) but for a model run that "looked" like a pure or mostly pure snow event...this looks very underwhelming: (it's a 1-4" event for us. and the storm has moved out at this point)

Fog has burned off and the sun is shining brightly. Currently 49 degrees. Only received .03" of total QPF yesterday. Very disappointing. We had an hour or so of light snow/sleet/rain and that was it.

Over half of Lanco is in the 4-5" area.

The actual snow map (why am I even talking about stupid snow maps, but I digress) is much less than that...though still impressive. There is a lot of mixed precip in that storm that is not snow but is counted in those maps.

@Bubbler86 - it does not appear as if MU saw any snow this morning.

A quick Google search shows that there are various interpretations of this - including what Bubbler was told about the upper valley being in NY state.
