As we close March, we close the book on a #heatwave without precedent, one meteorologists simply didn’t think was possible. As per @extremetemps research, in total 17 States set new all-time March maximum temperature records in the last 10 days… 1/

This is just absurd. Flagstaff AZ has gone 10 straight days with record highs above their previous all time MONTHLY MAXIMUM for March (73F). No stretch this warm has ever been recorded there even in April! You have to go to early May to get warmer values. Data back to 1893. An unprecedented event.

Crazy stats from Flagstaff AZ. Today will be their TENTH day in a row with a highs greater than their previous all time monthly March maximum of 73F. The week of Mar 18-24 averaged highs of 78F, more typical of mid June, and a full 10F greater than the next warmest week. Historic early heat wave.

Record hottest March day in Kansas.. 104F (40C) in Hugoton. Beats previous March record of 101F (38C) set 5 days ago. Also 104F (40C) at Ashland via KSU mesonet network if verified. Other notable hot spots: Medicine Lodge: 103F Liberal: 102F

As of today (Mar 22), Flagstaff AZ has recorded 5 straight days with max temps above its previous all time March monthly maximum (73F) NWS is forecasting another 6 straight days > 73F. Exceeding a monthly max for 11 straight days must be some sort of climate record. Off the chart stuff.

Never seen anything like this. 200+ monthly records set today alone! Every pink dot means a city set its new all-time highest March temperature! That’s around 570 new monthly records in the last 4 days. Some set multiple times. By far the most rogue #heatwave the US has experienced in memory.

This March heat wave over the SW US is mind boggling. Before this event, Flagstaff's all time March high was 73F. They have exceeded that mark the past 3 days, and are expected to exceed it for at least the next 7 days! Breaking your all time monthly record 10 days in a row?! I've never seen that.

A record high of 18.0C in Calgary AB today, beats previous record for Feb 5th of 17.4C in 1984. It’s the earliest in the year they’ve ever hit 18.0C or more (previous earliest date was Feb 12 1934) and ranks as Calgary’s 8th warmest February day on record (data since 1885)

A fine looking early February day in southern AB. Already 15C as of 10:40 am with beautiful blue skies, and a gusty southwest wind. Heading up to a record 20C this afternoon.

Canadian snowbirds don't have to head to Florida for warmth this winter.. head to southern Alberta instead! Temperatures expected to hit the 20C mark today in south AB while Florida struggles in the low to mid teens this aftn. A good example of the warm west/cold east pattern we've been having

Incredibly mild early February day in southern AB. Several sites hit the 20C mark, including Lethbridge with a record high of 20.6C, 2nd warmest Feb temp on record there (21.8C on Feb 27 1992) Hot spot was Hays at 21.3C. Calgary tied a daily record high for Feb 4th at 16.2C (tied with 1992)

St Catharines already up to 29C as of 9 am. Likely hitting a record high 35C this afternoon. Recall that two days ago Env Canada was forecasting a *high* of only 27C for St Catharines for today. Faulty forecast algorithm leading to poor temperature forecasts in Niagara.
