September 21: Hot And Humid For A While, Daily Links

WEATHER

Even though autumn officially arrives tomorrow, more hazy, hot and humid weather is in store for us over the next several days.  Temperatures tonight will only drop to the upper 60s, with patchy dense fog developing, much like the last several mornings:

We’ll warm right back up to the mid to upper 80s Friday afternoon:

Heat indices will run just over 90°:

More of the same over the weekend:

Just a very slight storm chance tomorrow through early next week — the daily 10-20% chance is more typical of late July rather than late September:

The overall weather pattern won’t shift until late next week — a cold front will bring a better chance of showers and thunderstorms Thursday, and a significantly cooler air mass in time for next weekend:

We’re still tracking the same two tropical systems in the Atlantic Ocean:

Jose will drift around for the next few days, weakening as it does so:

Maria is back to Category Three hurricane status, but it will also weaken as it stays offshore over the next five days:

The various forecast models on the “spaghetti plot” all agree with that offshore forecast — still, we’ll keep a close eye on the storm over the next several days:

    Shades of 1891?! That September also got off to a record cool start (which it held until this month), only to flip completely for the latter half, so much so, that it ended up on the warmer side. September 2017, probably, won’t repeat that feat but, before the eventual cool-down arrives to close out the month, the temperature deficit should be slashed considerably. As of yesterday, month-to-date average was 3.2 degrees below the norm (it was 8.6 below 8 days prior), so, we’re likely to witness two consecutive months of below-average temperature for the first time since January-February 2015, a seemingly distant past.

      If the numbers in our 7-day forecast pan out, we’d end up back to EXACTLY normal for the month. 71.5 degrees. Quite a turnaround!

    Actually, I’m secretly hoping for that!
