This record cold March at Fairbanks is even more amazing when you consider how much above normal it was in the Arctic (80+N) in March: You can see evidence of this stark contrast of cold anomalies to the warm anomalies to the north in the Arctic as well as to the south in the lower 48 on this for March 1-17:

We’ve talked about UHI being a nontrivial portion of Phoenix’s warming. I’ve brought it up, myself. But, note as you may already realize that the UHI affects the warming of lows more than the warming of highs (assuming I’m not mistaken).

Hey @Stormchaserchuck1any thoughts about this? Fairbanks is progged to have its coldest DJFM on record with it ~-13.1F! The current coldest DJFM: 1965-6: -12.9F El Niño 1970-1: -11.6F La Niña 1933-4: -11.1F La Niña 1917-8: -10.6F La Niña By a margin of 2F, they’re progged to have their coldest March on record at ~-8.6F!

They forecast based on population weighted because their forecasts are for the purpose of forecasting AC usage as opposed to what you look at, which isn’t pop weighted. Does that relate to your post?

Followup: Fairbanks is progged to have its coldest DJFM on record with it ~-13.1F! The current coldest DJFM: 1965-6: -12.9F El Niño 1970-1: -11.6F La Niña 1933-4: -11.1F La Niña 1917-8: -10.6F La Niña By a margin of 2F, they’re progged to have their coldest March on record at ~-8.6F! This feat is extra amazing because the Arctic has warmed the most due to GW! Link to data that allowed me to calculate this out: https://www.weather.gov/wrh/Climate?wfo=afg

After yesterday’s KSAV record tying high of 89, today’s was only 69, which was just after midnight. It stayed in the 60s through the afternoon along with some clouds much of the day, breezy NE winds, and dewpoints mainly upper 30s to 40 making for a pleasant walk. It’s now down to 56. Tonight’s low is forecasted to be in the upper 40s.

1. How about this? Phoenix had its coolest high in 11 days by a good margin (96) and yet it was still another record high, the 14th of this month! 2. Believe it or not, the next two days’ record highs of 97 are forecasted to be close to being hit. So, two more daily record highs are possible! 3. The morning low was 75. IF it doesn’t cool down to 74 by midnight local time, it would be not only a new record high low for today, it would become the new monthly record high low and the earliest 75 low by far with the current earliest being way out on April 19th! The current record for the day and month is 74, set way back in 1986.

+0.3. This month will likely be ~10 times as high!

This summer forecast is from pro-met Travis Hartman of Vaisala Xweather. I received this yesterday free of charge as I’m not a paying client. “What kind of summer are we walking into? For 2026, the early answer is: another warmer-than-normal season in the US and Europe with important regional caveats. Ocean signals point to warmth A major driver of the expected heat is the ocean. Global sea surface temperatures remain historically warm, and the North Atlantic is firmly in its positive multidecadal phase, also known as warmer-than-average Atlantic Multidecadal Oscillation (+AMO). In plain terms, the Atlantic has been running hot for decades, and warm oceans amplify heat on land. A warmer Atlantic tends to pump up the Bermuda High, helping lock in warmer conditions across the Eastern US. Enter El Niño—but with nuance Models suggest that El Niño will develop through the summer. Historically, El Niño can take some of the edge off the heat in the Midwest and East by shifting the jet stream. But whether that cooling influence is realized depends on an unlikely character: West Pacific typhoons. Their recurving paths can tug on the jet stream in ways that promote cooler conditions across the US. Fewer typhoons, on the other hand, leave the hotter background state unchallenged. And recent decades have seen a trend toward fewer summer typhoons overall. So, what does this mean for 2026? The forecast calls for summer 2026 to rank as the 11th-hottest since 1950, with the strongest confidence in significant heat across the West and South. The Midwest and East are the wild cards—torn between ocean-driven warmth and the possibility (but not the guarantee) of El Niño-related moderation.”

Thanks, Ray. We all know that there’s lots of uncertainty this far out. It’s his bombastic style of Tweeting as if there’s little uncertainty about a super Nino that I’m noting just as he did in the first half of Jan for a supposed near record strong WWB that never occurred. @snowman19was the first to point his bust out. By the way Eric never acknowledged his big bust on Twitter.

How many times within a short period of time is Eric Webb going to Tweet essentially the same thing regarding his feeling about a near certain super Nino being jump-started by a very strong WWB? Does anyone recall when he kept Tweeting over and over about a near record strong WWB occurring in Feb. that never occurred? He loves to be bombastic as this is just one example. His being repeatedly bombastic doesn’t make it the near certainty he wants us to think it is. Snowman, Don, and myself commented about this being a big bust in the 25-26 thread:

How many times within a short period of time is Eric Webb going to Tweet essentially the same thing regarding his feeling about a near certain super Nino being jump started by a very strong WWB? Does anyone recall when he kept Tweeting over and over about a near record strong WWB occurring in late Jan that never occurred?

Coldest ever recorded in March anywhere on the globe occurred yesterday in Vostok, Antarctica with -76.4C or -105.5F! https://www.facebook.com/MikeCollierWx/photos/big-time-coldearlier-today-vostok-station-in-antarctica-recorded-a-temperature-o/1462495788561020/?

It looks like that finally Phoenix didn’t 100. It was “only” 99 today.

Anthony, I wouldn’t say that because the DJF AO was the most negative since 2020-1 with ~-1 averaged out.
