SACRUS Posted October 9, 2022 Share Posted October 9, 2022 Was down at 33 and now up to sunny 64 and gorgeous out. A bit breezy but nice. Dry and warming the next 3 days / though Wed (10/12). May touch 70 / low 70s in places Tue and Wed. Watch front and low on Thu which could bring some rain/storms / wind. We'll see if we clear out Friday (10/14) or clouds and showers linger. Otherwise next weekend Sat (10/15) and Sun (10/16) look dry and near normal before deep trough and next strong cool shot moves in by Mon (10/17). Looks chilly through the middle of the next wok week. We'll see there is a warmer rebound sustained in the cards for the close of the month. 2 Link to comment Share on other sites More sharing options...
donsutherland1 Posted October 9, 2022 Share Posted October 9, 2022 After the coolest morning so far this season, temperatures rebounded into the lower 60s on a sun-filled October day. 12 Link to comment Share on other sites More sharing options...
donsutherland1 Posted October 9, 2022 Share Posted October 9, 2022 After a very cool start that saw the mercury approach record lows in a few locations, the temperature rose into the upper 50s and lower 60s across much of the region. Through 5 pm, highs included: New York City: 61°; Newark: 61°; and, Philadelphia: 65°. Nevertheless, the first 10 days of October remain on track to be much cooler than normal. The temperature will likely average 5°-6° below normal during the October 1-10 period, even with the return of milder air starting tomorrow. However, more cold air could arrive late next week sending readings below normal for another weekend. Out West, Portland saw the temperature reach 80° by 2 pm PDT. That was the 7th 80° high temperature this month. The old October record was 6 days, which was set in 1952 and tied in 1980 and 1991. Since 1950, 15/21 (71%) of cases with an ENSO Region 1+2 anomaly of -0.75°C or below were warmer than normal in the Middle Atlantic region, including Philadelphia and New York City. 48% were 1° or more above average in New York City and 62% were 1° or more above average in Philadelphia. Just 14% were 1° or more below normal in New York City while 24% were 1° or more below normal in Philadelphia. One-third of cases in both cities saw a monthly mean temperature of 60° or above. Overall, such ENSO conditions also favored warmth in the Central and Northern Plains, along with dry conditions in the Plains States. October 1988 was the coldest exception. The closing week of September saw the coldest Region 1+2 anomaly since September 1988. That development has increased the probability of a cooler outcome this month. A cooler than normal October is the base case. The ENSO Region 1+2 anomaly was -1.7°C and the Region 3.4 anomaly was -0.8°C for the week centered around September 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.88°C and the ENSO Region 3.4 anomaly has averaged -0.88°C. La Niña conditions will likely persist through the fall. The SOI was +24.11 today. The preliminary Arctic Oscillation (AO) was +2.905 today. The previous record high was +2.709, which was set in 1990. On October 6 the MJO was in Phase 5 at an amplitude of 0.813 (RMM). The October 5-adjusted amplitude was 0.717 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 71% probability that New York City will have a cooler than normal October (1991-2020 normal). October will likely finish with a mean temperature near 55.9° (2.0° below normal). 3 1 Link to comment Share on other sites More sharing options...

I use apps on both. But I have 8 different forecasting apps on my iPhone (plus radar and other weather apps). Weather Underground has their hourly forecasts on PC, and I assume some others do as well. Dark Sky is going to be gone by the end of the year, but that app was probably the best for when precip was expected to arrive and how long it will last. I just discovered Windy.com on my PC, which shows very specific forecasts, which you can tailor to your exact location, for rain, wind, precip, etc...from 5 different weather models, with some going out 7 days. Interesting to compare different forecasts temp, precip totals for different time periods, wind flow, specific, forecasted wind speed and direction, etc... 1 1 Link to comment Share on other sites More sharing options...

Still got awhile to go here-- it's very rare to get an October freeze where I am right now-- it's only happened twice in the last 30 years. Are you near MJX?

There can be cases where they are in different states. Wave lengths are still relatively short, so the influence of the AO+ has been offset. 2 Link to comment Share on other sites More sharing options...
