CIK62 Posted April 3, 2021 Share Posted April 3, 2021 The next 8 days are averaging 52degs.(44/60), or about +2.0 (I had 28/39 yesterday) 33*(43%RH) here at 6am. 32* at 6:30am. 35* by 9am. 40* by Noon. 42* by 1pm. 45* at 2pm. 50* by 3:30pm. 54* around 5:30pm. 46* by 7pm. T rises quickly this AM and stays in and around normal till after the 10th. Dry till that same time too. btw: 1967 had virtually every summer season weekend as a rainout, or a threat to rain, and kept crowds away. It was compared to the 1903? rainouts business disaster in CI. Link to comment Share on other sites More sharing options...

wdrag Posted April 3, 2021 Author Share Posted April 3, 2021 No thread on my part but three more opportunities for snow lurk in our subforum. later tonight ne PA/nw NJ, probably no big deal tho 1/2" possible higher terrain ne PA. Then the 9th-11th (next Fri-Sun), Potential for a pretty big long duration periodic rain event (1"+) with wind (40kt) for a part of the sub forum coast with high terrain wet snow possible. Ensembles don't favor snow, certainly nothing like the 00z/3 EC snow depth forecast (just nw NYC). There's even something during mid month? Keeping an eye on it. Figure future modeling will shrink the snow, not sure the sizable storm will disappear in what appears to me to be a favorable blocking pattern for a slow mover somewhere along the Mid Atlantic Coast. 6 1 Link to comment Share on other sites More sharing options...

It looks like we could see a slow moving cutoff with the blocking to the north. I have noticed that the new OP GFS v16 beyond 120 hrs has tried to cut storms to our west with blocking last winter. It seems to adjust south as we get closer to 96-120 hrs. Even the GEFS has a slow moving system going underneath to the Mid Atlantic coast. It could wind up being a substantial rain and wind maker for the area with some frozen further NW as Walt mentioned. We'll see. 4 Link to comment Share on other sites More sharing options...
donsutherland1 Posted April 3, 2021 Share Posted April 3, 2021 Morning thoughts... Across the region, temperatures again started at or below freezing. At Allentown, the low temperature of 20° tied the daily record set in 1954. Saranac Lake reported a near record low of just 2°. The cold start will give way to a warmer afternoon. Today will be mostly sunny and milder. High temperatures will likely reach the lower and middle 50s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 54° Newark: 55° Philadelphia: 55° The warming trend will continue through the weekend. Out West, there is a chance that the temperature could make a run at 100° at Phoenix for the first time this year tomorrow. Should the temperature reach the century mark, that would be the 3rd earliest such temperature on record for Phoenix. 1 Link to comment Share on other sites More sharing options...

So often it'll be a sea of warmth with a little cold and/or gloomy pocket in the northeast to New England. You dont even have to go that far for a much nicer springs. Just to Philly its noticeably better and a DC spring will make you think you traveled way more than just a couple hundred miles. Also this super dry air is an asthma nightmare, esp combined with pollen. When can we get dew points consistently 40+, and be totally done with single digits like today. 1 Link to comment Share on other sites More sharing options...

Yeah, the low humidity season usually peaks in March and April here. Things should gradually moisten back up going into next week. Then it looks like our next chance of significant rain again in about a week. We saw this in March when we went from very dry to wet again. The main take away is that dry patterns don’t have much staying power in our new wetter climate. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=157&network=NJ_ASOS&station=EWR&year=2020&var=min_rh&dir=below&thres=20&dpi=100&_fmt=png 1 Link to comment Share on other sites More sharing options...

The erratic weather that's still too cool for summery activities, mud season, fog season, wind season, allergy season, dry/fire season, bug season, too cold for beach/lake, the end of winter.

The season we just left is the one I’ll soon be a permanent part of. April being my birth month, I will always have a special fondness for. My favorite American poet, Paul Simon, said and sang it best; “ April come she will. When streams are ripe and swelled with rain” the summer and fall will follow until, as Paul says, “A love once new has now grown old” being alone and near the end give the words a greater meaning to me.

donsutherland1 Posted April 3, 2021 Share Posted April 3, 2021 The region started with readings at or below freezing for a second consecutive day. However, the strengthening April sun boosted temperatures into the 50s in much of the region during the afternoon. Elsewhere, daily record low temperatures were set or tied. Daily records included: Allentown: 20° (tied record set in 1954) Charleston, SC: 31° (old record: 33°, 1962) Charlotte: 26° (old record: 28°, 1972) Columbia, SC: 28° (tied record set 1992) Jacksonville: 36° (old record: 39°, 1962) Savannah: 32° (old record: 33°, 1966) Sherbrooke, QC: 9° (old record: 28°, 2008) Wilmington, NC: 30° (old record: 31°, 1992) Meanwhile, in the Southwest, Phoenix reached a record-tying high temperature of 97° today. That warming trend will tomorrow into early next week. Temperatures will likely return to the 60s in parts of the Middle Atlantic region tomorrow and then in much of the region on Monday. Historic experience following a warm to very warm March suggests a probability that is skewed toward a warmer than normal April. That warmer scenario remains the base case despite the current strong cold shot. The ENSO Region 1+2 anomaly was -0.9°C and the Region 3.4 anomaly was -0.6°C for the week centered around March 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.15°C and the ENSO Region 3.4 anomaly has averaged -0.67°C. La Niña conditions will likely give way to neutral-cool ENSO conditions as the spring progresses. The SOI was -0.46 today. The preliminary Arctic Oscillation (AO) figure was +0.533 today. On April 1 the MJO was in Phase 5 at an amplitude of 1.398 (RMM). The March 31-adjusted amplitude was 1.297 (RMM). 1 3 Link to comment Share on other sites More sharing options...

LibertyBell Posted April 4, 2021 Share Posted April 4, 2021 12 hours ago, bluewave said: It’s very challenging to get wall to wall warmth here during March, April, and May. The NYC average temperature in March is 42.5°...April 53.0°...May...62.4°. So the springs that everyone remembers as warm usually went 45°..55°...65°. So 3 consecutive +2 to +3 spring months. We had the 45°+ March and 80° record warmth. But the record cold to start April reversed the March pattern. The only 3 years I can find were 2012, 2010, and 1985. NYC....45....55....65....springs since 1981 2012 50.9 54.8 65.1 2010 48.2 57.9 65.3 1985 45.8 55.5 65.2 why is it that these months were much warmer in the 90s and early 00s?
