April outlook - will the warmth continue?


Isotherm

Recommended Posts

We have to watch for a miller B coastal re-developer for Sunday. Most models hint at it and so do a lot of euro and gfs ensemble members.

12z euro ensembles are pretty wet Sunday into Monday now with an overunning type event developing into a coastal.

The 0z euro ensembles have .50"-.75" of rain for Thursday.

And then a wet weekend also with another .50"ish.

From Southern Cali to the Pac NW in a week. Still looks like the ridge will dtart to build east by the beginning of May. Hopefully we can salvage Fri and Sat.

50 F, cloudy, and breezy - love it.

Looks like we'll have a nice cool end to April.

12z GFS has us in the 40s/50s this weekend into early next week w/ strong Canadian high pressure. Probably multiple frost/freeze opportunities in suburbia over the next week, starting with tonight. Should be temporary though; I think the cool is headed out after the first few days into May.

From what the gfs shows, I would not be surprised if we saw some frozen precip this weekend with temps possibly dropping into the upper 30s around here when the rain comes in. If the system was stronger with more precip and if the high north was stronger, maybe some snow could have been in the cards, but we'll see what happens.

Yeah, if we had this pattern a month ago we'd probably we talking a moderate snowfall. It's funny how mother nature gave us the classic bookend winter -- biggest northeast snowstorms in Oct and April.

Not saying it will snow but we thought it couldn't snow in October either, so late April wouldn't exactly be shocking.

Hopefully it is way too late to give any snowfall where it is almost May for christ sakes and it has only snowed twice in May for NYC since records where kept. Never yet measurable snow has occurred.

The setup wasn't was exactly the same it was in late October the same then it was now plus we were talking about a much stronger storm in October to allow more colder air daming to allow to snow to happen. This looks more of a overrunning event with a possible weak Miller B developing oppose to a classic Noreaster. I am saying we can't see any snowflakes or any frozen precipation at all but accumulating snows is highly unlikely though. I prefer personally to wait until next season to see my snow.

Support is growing for some type of swfe/coastal miller b re-developer for the Sunday timeframe.

GFS has temps of 36-38 degrees with precip falling, even in the city.

Euro looks about the same, maybe even a tad colder.

Other globals agree as well.

Are you kidding me highs in the 30's with snow. I hope the models are on crack. Look at this at worse I could see highs in the mid 40's with cold rain with some sleet mixing in and maybe some wet snow just north of the city.

And this looks more like a overrunning event than anything else with possiblity a weak miller B

Yesterday was a -6 departure and the 3rd consecutive negative departure in a row. The next 2 days will be close to average but then we can see -6 to -10 departures to finish April.

Looks like we will finish the month of April +2 to + 3.

Models now locking in a .25"-.50" rainfall for Thursday.

We have to watch for more as well. The 6z NAM has .75"-1" of rain.

NAM with its .75" of precip for tomorrow might not be overdone. Euro ensembles also have .50"-.75" of precip. Estimate .60", looking at the position of the precip shades.
