    Under abundant sunshine, the mercury surged into the upper 60s and lower 70s across much of the region. High temperatures included:

    Allentown: 69°
    Baltimore: 75°
    Boston: 70°
    Bridgeport: 64°
    Hartford: 70°
    Islip: 70°
    New York City: 68°
    Newark: 74°
    Philadelphia: 71°
    Portland: 66°
    Providence: 71°
    Washington, DC: 73°

    Newark reached 70° for the 176th time this year. The old record was 173 days, which was set in 2010. Four of the five years that saw 170 or more such days have occurred since 2000 and three have occurred since 2010.

    With the exception of Thursday, the unseasonable warmth will persist through Friday. Nevertheless, the first 10 days of November will average solidly cooler than normal in the Middle Atlantic and southern New England regions. A cold front will bring some rain Thursday night into Friday. A general 0.50"-1.50" rainfall is likely. Afterward, it will turn noticeably cooler for the weekend and into next week.

    Fall 2021 will likely be wetter to much wetter than normal in the northern Middle Atlantic region. Since 1869, there have been 9 August cases where New York City picked up 20.00" or more rainfall during the summer. Two thirds of those cases (and 4/5 of those with summer mean temperatures of 73.0° or above) had 17.00" or more fall precipitation in New York City. 2011 is probably the closest match in terms of precipitation and a nearly identical summer mean temperature. Mean fall precipitation for those 9 cases was 14.86". The median was 17.35". The 1991-2020 normal value is 12.27". Fall rainfall through November 9 4 pm is 15.29".

    Following very wet July-September periods, winter (December-February) precipitation has typically been near or below normal. The most recent exception was winter 2018-19.

    The ENSO Region 1+2 anomaly was -0.8°C and the Region 3.4 anomaly was -1.0°C for the week centered around November 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.27°C and the ENSO Region 3.4 anomaly has averaged -0.78°C. La Niña conditions will likely persist through at least mid-winter.

    The SOI was +20.61 today.

    The preliminary Arctic Oscillation (AO) figure was +1.143 today.

    On November 7 the MJO was in Phase 4 at an amplitude of 1.113 (RMM). The November 6-adjusted amplitude was 1.184 (RMM).

    Based on sensitivity analysis applied to the latest guidance, there is an implied 57% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 47.6° (0.4° below normal).

     

    What's happening on Thursday that's going to keep the region from being above normal?

    October will start with record blocking over Eastern Canada. The weeklies continue  this general 500 mb pattern right through October. It’s interesting since several long range seasonal forecasts were showing this type of October regime since last summer. So plenty of Canadian high pressure to our north.

    What does this mean temperature-wise?

  3. On the next rain forecast:

    On Saturday evening (Eastern), there will be two rain systems, one over Montana and the Dakotas, and the other over Colorado and Arizona, which will be moving toward each other.

    There are two scenarios that could happen:

    Scenario 1: The two systems fuse together into a powerful storm over Nebraska and South Dakota early Monday morning. It will cross over the Midwest on Monday and reach us by Tuesday.

    Scenario 2:  The two systems stay away from each other. The Arizona/Colorado system eventually reaches us on Wednesday.

  4. Updated forecasts

    Monday: Still looking nice and dry.

    Tuesday: The models seem to be coming into agreement here that there will be some rain on Tuesday. The GFS shows light showers spread out over several hours, the Euro has a heavier but shorter lived storm. Ultimately the two both come out to about a quarter-inch of rain.

    Wednesday: Still likely to be the wettest day of next week. The timing is still up in the air. It’s midday storms on the Euro and a late night rain on the GFS. The Euro is much wetter on this than the GFS.

     

     

  5. doesn't look like we will reach 90 - this mornings GFS once again keeps temps well below 90 for a couple weeks . First we have to break out of this pattern we are in with troughing in the northeast

    you can really see what is going on with this loop

    Is this what gave us the year without a summer in 2009?

  6. Looks like we will not have any 90 degree days in May this year -

    Also if we have a cooler summer we can avoid the increasing chances of electrical blackouts - we almost had a widespread one this past winter

    It looks like we have a shot for some 90s next Wednesday and Thursday.
