WB 18Z EURO AI and EURO

WB 21Z NBM storm totals.

I think it will show some three footers this year if it is not...

And not over yet....maybe we should wait until after this winter to retire the NAMs...

WB 12Z ensemble for the potential tropical remnants; still a lot of spread.

Let's see how the Northern Hemisphere snow/ice map looks by November....

Heavy shower moving through!

WB 12Z EURO for weekend.

WB 9Z NBM for the weekend. (Most of the light precip. falls on Sunday.)

It is pathetic that the flip flopping EUROs are the best models we have in 2026.

WB 9Z NBM: models went south overnight...

WB 18Z EURO compared to 0Z.

WB 18Z EURO is wet Saturday with frontal passage.

Lesson learned for me is that the EURO flips like every other model. Will not get my heart set on a storm track outside 48 hours anymore.

WB 18Z EURO AI compared to 0Z.

No idea what will actually happen, but today trended wetter for the weekend especially DC south.

NWS Sterling for Sunday.... like most systems we are in wait and see mode. A wave of low pressure, infused with tropical moisture from the remnants of multiple East Pacific systems, treks toward the OH/TN Valleys Saturday into Saturday night. The track of the low beyond this point will depend on (1) where exactly the stalled front is, and (2) the strength of a transient blocking high pressure to the north. Rain or showers become increasingly likely for much of the region Saturday night into Sunday, with a soaking rain possible if the wave of low pressure is a bit more organized/closer to the area.
