Beautiful day across California on Saturday with some mountain snow showing up in Sierra. Lake Tahoe opening in 2-weeks … we’ll see if the cooler weather and troughs from Alaska and Canada will mean consistent snowfall through November, or if the Pineapple Express (atmospheric rivers) turbocharged by El Niño will dominate.

\"\"

Area of low pressure with Pacific subtropical moisture firing severe storms across New Mexico and West Texas this evening. A frontal boundary with much cooler, seasonable air behind it from Canada is heading into the Great Lakes for Sunday.

\"\"

A small storm system is swirling off the Washington State coastline with welcome rainfall, and some gusty winds, but not particularly extreme.

\"\"

Low Temperatures Sunday Morning

\"\"

Seeing 20s in the Midwest — and even teens up in Prairies of Canada. Also 20s and lower 30s in the Northeast. About 15 million below freezing.

\"\"

High Temperatures on Sunday

\"\"

Very warm 70s in the Great Lakes — 60s in Northeast. Very comfortable, beautiful late October day. It could be a lot cooler!

Integrated Vapor Transport Next 10-days | ECMWF AIFS 12z

\"\"

Hurricane Vance dissipates in the mouth of the Gulf of California and its moisture is pulled into the subtropical jet stream out of the Pacific —> that becomes the dominant weather pattern and flow in into weekend —> which is WARM across the Eastern half of the U.S.

Otherwise, not seeing any atmospheric rivers for the West Coast.

Height Anomaly Pattern | Next 10-days

\"\"

Parade of troughs dipping across the West Coast — and ridging east of the Rockies.

Bomb Cyclones — Second of three to affect United Kingdom and Western Europe

\"\"

One more powerful bomb for early next week. Barometers across Scotland were getting a workout today.

\"\"

850 mb winds (1.5 km up) to show the strong “chevron shaped” band of often hurricane force winds on the back side of the powerful bomb cyclones. This was a major chunk of my dissertation back at Florida State more than 2-decades ago.

Blend of Models Precipitation Next 7-days | Lower 48

\"\"

My favorite parameter — precipitable water | ECMWF 18Z next 6-days

\"\"

Bit of a subtropical / cut-off low east of Florida but no tropical development likely. That moisture gets dragged westward across the Gulf

Temperature Analysis at 8:00 PM ET

\"\"

Temperature Analysis | Anomaly from Normal

\"\"

Lower 48 was -0.8ºF below normal

High Temperatures next 9-Days | Mild Late October (way above normal)

\"\"

NWS NDFD Next 3-days precipitation

\"\"

New RRFS Model Snowfall Next 84-hours — Model becomes operational on November 3rd — alongside HRRR.

\"\"

Blend of Models Snowfall Next 7-days

\"\"

Still waiting on our first Eastern U.S. snowfall through first week of November.

Snowfall Next 15-days | ECMWF Ensemble 12z Median

\"\"

Slowly but surely as these maps head into early November — we’ll see our first chances of a snow storm for the Midwest, Great Lakes, and Northeast — not yet.

Probability of 1-inch or more of snowfall through November 8th

\"\"

Week 1 Temperature Anomaly | Oct 24 - Oct 30

\"\"

Week 2 Temperature Anomaly | Oct 31 - Nov 6

\"\"

Blow torch first week of November across Eastern U.S.

North Atlantic Hurricane Season

No areas of interest from NHC … I think this is curtains as November is typically quiet.

\"\"
\"\"

EPS 12z had nothing tropical in the next 10-days.

\"\"

I think we can conclude the Atlantic hurricane season updates unless something pops up.

Eastern Pacific Hurricane Vance — but will weaken

\"\"

No other areas of interest in the Eastern Pacific, but perhaps something west of Hawaii in the Central Pacific (30%) chance.

\"\"

Along the International Dateline — area of disturbed weather could drift eastward toward waters west of Hawaii in the next week.

\"\"

Western Pacific Typhoon Basin | In-fa (30W)

\"\"

JTWC up to Category 4 — potential for yet another Super Typhoon

\"\"

Weather Next 3 median intensity was 142 knots (Category 5)

\"\"

A cool track animation — forgot I made these, so I need to show them off.

\"\"
\"\"

Northern Indian Ocean | Invest 98B —> powerful Cyclone w/median intensity of 130-knots = strong Category 4+

\"\"
\"\"
\"\"

HAFS-A down to around 969 mb —> Major Hurricane Intensity landfall late Tuesday / Early Wednesday along Indian coastline.

\"\"
