Huge Storms Pulls Away, Cold Left Behind

Well that massive cold front and area of low pressure is scooting out of the picture, but not after doing a lot of damage and producing over 50 tornadoes in 2 days!

Behind, we're getting the first real taste of the cold season with widespread frost and freeze advisories in place - shown in light and dark blue on the map below.

Record "Bomb" Storm System

A new record set today on Tuesday for the lowest pressure in a non-tropical storm in the mainland U.S.

The massive storm system barreling across the central U.S. had a minimum central pressure of 28.24" or 956 mb (equivalent to the minimum pressure of a Category 3 hurricane).

This breaks the old record of 28.28" (958 mb), set on ...Jan. 26, 1978, during the Blizzard of 1978 (aka the Cleveland Sueprbomb).

This is also lower than the March 1993 Superstrom (aka "The Storm of the Century"), or the "Witch of November" storm that sank the Edmund Fitzgerald in 1975, or even the Columbus Day Storm of Oct. 1962.

New low pressure readings were also set for the states of Minnesota and Wisconsin.

The storm generated hurricane force wind gusts from Colorado to Michigan - tipping over semis, downing power lines and making it almost miserable to be outside.

In North Dakota, the winds whipped around snow - making blizzard conditions exist nearly statewide.

Upper Midwest Low Pressure

What an amazing storm system right now in the middle of the country!  Tornado warnings along a cold front that extends from Louisiana to Michigan.

There is a high risk for tornadoes today across northwest Ohio and vicinity.

This low pressure has "bombed" out - meaning it rapidly intensified at the rate of the pressure lowering 1mb per hour for 24 hours - that happens over water but not too often over land.

Changing of the Seasons

Well I love this time of the year - the transition during the fall season can make for very colorful maps - such as the one for today in the picture below.

Everything from winter storm warnings in the pink across the central Rockies to tornado watches in the southeast (in yellow). Even severe thunderstorm watches in the rose color across the Carolinas and Virginia.

In between, all the brown means high wind watches and warnings - as the two air masses battle it out today.

Expect a windy go of it today across the center of the country - esp. from Texas to Michigan.

I am sure there will be a lot of bumpy landings and takeoffs today on the US air system.

Paula To Fizzle Out

Hurricane Paula is no more!

The storm is now just a tropical depression and will soon be nothing more than a remnant low.

But that doesn't mean the weather will clear for extreme south Florida, the Keys and Hispanola.

There will still be some scattered showers and storms from time to time, not to mention some choppy waters off the coasts.

Engineering Innovations Breakfast

If you are in the Boulder, Colo. area next week - mark your calendars for a great networking and learning opportunity.

The next Engineering Innovations Breakfast will take place at the Boulder Marriott on Tuesday, Oct. 19, when Colorado State Climatologist Nolan Doesken and CoCoRaHS National Coordinator Henry Reges explain the unique volunteer precipitation data-gathering network that is CoCoRaHS.

Volunteers in all 50 states now send in data daily, and the information is used by NOAA, the National Weather Service, insurance adjusters, farmers, city utilities, and other professionals who need high-quality data about weather and precipitation. Doesken and Reges will discuss the kind of research that this unique data makes possible.

The breakfast will be from 7:30 to 9 a.m. at the Boulder Marriott. RSVP today by calling (970) 491-3110 or e-mailing

Admission for each breakfast is $20 per person ($15 for breakfast and a $5 gift to the Dean's Innovation Fund; cash or check only). Payment is accepted at the event. Hope to see you there!

Wild Western Weather

I saw things I've never seen this time of year on the weather maps yesterday - tornado watches/warnings in Utah and Arizona.

As well as severe thunderstorm watches/warnings in those states and Colorado too.

The storms actually left behind several severe weather reports, mostly in Arizona and Utah, including a few tornadoes.

Some of those storms even held together and rolled from the foothills into the Denver metro area around midnight.

Extremely rare for October.

When people talk about global warming, the put so much focus on the temperature. I actually don't associate global warming with temperatures as much as I do with stuff like this - extreme and unusual weather patterns.

Snow In Tennessee, Tornadoes In Arizona

Whacky fall weather continues....with snow at the highest elevations of the Great Smoky Mountain National Park in east Tennessee.

Meanwhile, a potent area of low pressure cut off over the desert southwest continues to bring rain and cool weather to the region - along with strong to severe thunderstorms - including tornadoes near Flagstaff.

Stormy Night In The Desert

Showers and storms, a few strong to severe, are rumbling in the Phoenix-Tucson area of south Arizona tonight.

The monsoon season is over - but the late season rainfall is not.

So far we have seen heavy rain, 1 to 2 inch hail and winds 60-80 mph with some of the storms.

Taste of Fall Settles Into South

Check out this temperature map from just before 8 am local time, Tuesday, October 5.

It's in the upper 30s to upper 40s almost all the way down to the Gulf  Coast!
