Active Weather....Potentially 4 Tropical Systems, Nor'Easter & How This Affects Us

The Eastern Pacific is extremely active once more with tropical activity, including Category 5 Willa. These will all have an impact on U.S. weather. We will see indirect, but notable effects.

The low temperatures Sunday morning show the influences of Lake Michigan well.

Lake effect moisture & cloudiness keep temperatures near 30 to the mid 30s in the far east & northeast.

Meanwhile, clear skies & dry air allowed temperatures to reach as low as 20 in the south!

The 24 at Lafayette is more than 2 weeks earlier than normal.  It is the same at Covington & Crawfordsville.

Today has warmed nicely with temperatures reaching the low to mid 60s!  Winds are pretty strong with some gusts 25-30 mph.

It looks dry the entire week & breezy to windy at times as dry cold fronts pass through.

Some stratocumulus/cumulus clouds may pivot into our northeastern & northern areas tomorrow with a few clouds elsewhere tomorrow afternoon.  It will be rather breezy with north winds at 13-24 mph.

Wednesday will feature quite a lot of stratocumulus swinging in from Lake Michigan with highs only in the 40s to around 50 with northeast winds at 12-24 mph.

So we have Category 5 Willa, Tropical Storm Vicente & what may become Xavier off the west coast of central Mexico.

Two of these may move inland (what may become Xavier will tend to get whisked away westward farther out into the Pacific).

Flooding rainfall is likely Mexico to Texas & then getting into Louisiana.  In the northern Gulf, this may become Atlantic tropical storm or a hybrid subtropical storm Rafael.

This would tend to ride the Gulf Coast with strong winds & heavy rainfall with a final landfall on the northern Florida Peninsula.

However, whether it retains tropical or subtropical status or retains the name Raphael or diminishes & then resurges to become Sara remains to be seen.

All it will do here is bring a high & mid level overcast Wednesday night-Friday with cool, brisk northeast to east winds.  Temperatures will run in the 40s to the lower 50s.

Things get extra interesting next weekend.

A pretty vigorous, gusty Alberta clipper here with a few showers could morph into this tropical system or hybrid system off the East Coast.  Given that & the big difference in the very warm water off the East Coast & the colder air coming in over land & we could see an impressive Nor'Easter or hybrid storm develop.

This could bring wind, high tides & heavy rainfall to the East Coast with high elevation snows.  It looks like the storm will be strongest with the strongest winds when it is off the coast of Massachusetts & Maine.

Here, all it will do is keep it chilly, windy & mostly cloudy with a few showers as upper troughiness dominates Sunday-Monday.

It looks completely calm & sunny Tuesday, however, as strong surface high pressure quickly builds in.

It should warm up & turn windy for Halloween with showers & even a few t'showers passing.  After 40s/50s Tuesday, 50s/60s are possible Wednesday.

It still looks to get spring-like in early November & last until mid-month.  It is also looks quite stormy.  We may have multiple strong, powerhouse storm system bring heavy rainfall & severe weather to our area in the November 6-15 time frame.

There are a couple of set-ups in the pattern suitable for severe weather outbreaks from Indiana & Illinois to Arkansas, Texas & Louisiana.

This will all occur as deep trough dives into California with rainfall & ridging builds in the Southeast.

Much colder weather should follow with even some minor snowfall.  It should warm-up very nicely, it appears after Thanksgiving.
