donsutherland1 Posted April 30, 2019 Share Posted April 30, 2019 Parts of the region experienced the coldest temperatures this late in the season (April 29 or later) in recent years. Minimum temperatures Included: Allentown: 32° (coldest since May 14, 2013, 31°) Danbury: 29° (coldest since May 1, 2008, 28°) Bridgeport: 36° (coldest since May 1, 2008, 36°) Islip: 40° (coldest since May 8, 2017, 40°) New York City: 41° ( coldest since April 30, 2014, 41°) Newark: 37° (coldest since May 2, 2008, 37°) Philadelphia: 41° (coldest since May 14, 2013, 41°) Poughkeepsie: 29° (coldest since April 30, 2012, 28°) White Plains: 32° (coldest since May 1, 2008, 32°) The ENSO Region 1+2 anomaly was 0.1°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.05°C and the ENSO Region 3.4 anomaly has averaged +0.93°C. Conditions consistent with El Niño should persist into at least the first week of May in Region 3.4. The SOI was -4.26 today. Today's preliminary value of the Arctic Oscillation (AO) was -0.473. The implied probability of a warmer than normal April is currently near 100%. There is also an implied 96% probability that April 2019 will wind up among the 10 warmest April cases on record. The most likely range for April's mean temperature is 55.4°-55.6°. On April 28, the MJO moved into Phase 4 at an amplitude of 2.133 (RMM). The amplitude was somewhat lower than the April 27-adjusted figure of 2.268. Since 1974, there were four cases when the MJO reached an amplitude of 1.750 or above during Phase 2 during the April 20-30 period. The mean May 1-10 temperature was 58.8° vs. the 1981-2018 average of 60.2°. 75% of those cases were cooler than the 1981-2018 average. However, during May cases when the ENSO Region 3.4 anomaly was +0.50°C or above for the month, the May 1-10 temperature averaged 60.8°. Therefore, it is likely that the first 10 days of May will probably wind up with a mean temperature of 59.2°-61.2°. Going forward, May looks likely to be both warmer and wetter than normal. The latest EPS weekly guidance has swung from cooler than normal to near normal. The CFSv2 favors somewhat warmer than normal conditions. 1 Link to comment Share on other sites More sharing options...

Cfa Posted April 30, 2019 Share Posted April 30, 2019 Looks like I’ll fall just short of 10 consecutive days with measurable precipitation. Sucks because it did rain tonight, still drizzling actually. Edit: May have squeezed out a 0.01” at the last minute. More rain now falling. 1 Link to comment Share on other sites More sharing options...
doncat Posted April 30, 2019 Share Posted April 30, 2019 Will finish month with 17 days with measurable precip and about 4.30" total, which is 0.20" above station normal. That makes just one month out of the last 15 that had below normal precip. 1 1 Link to comment Share on other sites More sharing options...
CIK62 Posted April 30, 2019 Share Posted April 30, 2019 Last day of April to average 58degs., or 1deg AN Month to date is +2.6[55.5]. April should end at +2.6[55.6]. A tie for 7th Place, but really too close to call with rounding and differences with GFSx averages. All 8 days are averaging 61degs., or +3degs. 1 Link to comment Share on other sites More sharing options...

Yeah 70s to 80 in Philly, flirting with 90 possible in DC by Thurs. Everyone is dodging showers though. Either cool and dreary or warm and t storms.

Indeed- we definitely has frost here too. So much for that warm April lol, I've heat on every day of this month! It's been a yucky, cool, rainy month. Chicago got two historic late season snowfalls though. My idea of a warm April is lots of 80s and a few 90s, we haven't seen that since 2010.
