It is another day where temperatures are not only beating all-time March records, but also April records in Canada.  The heat extends into the northwestern U.S.

It is already 77 at Seattle's Tacoma Airport.  The low was just 59, making it a record warm low temperature for the date  This beat the old record of 57 set in 1900.

It is warmer right now, as of midday local time, at Fort Smith, Northwest Territories than our high temperature so far today as of 3:30 p.m. local time here.  It is sunny & 56 there & light rain & 45 here at West Lafayette.

It is warmer on the shores of Reindeer Lake, near Hudson Bay than it is here with 59 there.

Wildfires are now actually being reported due to the extremely warm, dry weather with incredibly early snow melt.  Dew points all the way to the northwest U.S. have been running in the teens & 20s & 30s, despite temperatures to 80.

It has cooled in Alaska.  It is back down to 25 at Fairbanks currently, but the chill has not made it farther southward to Klawock where it is 64 currently.


This ridge will try to move southeastward & build all the way to Texas, but it is the developing big East Coast Nor'Easter that will mess up our forecast of 6 days of nice weather with this ridge.

If we can push the Nor'Easter away & let the ridge come in completely, then 70s would be easy, but I think we will have to settle on 50s to 60s with three days of dry, nice weather instead, not six.

This is a large Nor'Easter with a deep moisture plume indundating areas way to the east.  Bermuda will is & will continue to be socked in rainfall with high winds.  Gale Warnings & Craft Advisories are up for the island.

Looks like we are going to split this spring weather into two pieces.  One piece will occur initially the end of this week to the weekend & then the other mid to late next week. 

In-between will be out brief, sharp cold snap.

Watch how the warm ridge begins to build southeastward & then it is halted a bit as the cold trough comes down around the East Coast storm tonight-Friday:

Note how that the short of potent cold air rushes in Monday as East Coast storm wraps up over far eastern Canada.

Also note how brief the cold snap is.  It is in & out in really 2.5 days. 

We are back to the 50s Wednesday, then 60s by late next week.

So, after scattered showers today-tonight & a bit of spotty rain/snow Thursday morning, it will be cloudy right up to Thursday afternoon before we begin to clear.

After lows 34-38 tonight, highs tomorrow will run 47-52 with brisk northwest winds at 13-24 mph.

Friday looks gray, cold, blustery & cloudy for the morning hours, then skies should clear.  After near 30 in the morning, we should see a late day rally of 50-57.

With frosty & clearing skies Friday night, lows of 27-30 are likely.

Saturday looks good with 58-64, followed by 30s Saturday night & increasing clouds with 50s to 60s Sunday.

With breezy conditions, some showers are possible late Sunday.

Showers & windy conditions are likely Monday with falling temperatures into the 30s.  Rain may end as snow.

With lows near 25 with clearing Monday night, wind chill will drop to the low to mid teens.

Tuesday looks bright, but cold with highs 36-41, followed by 20-25 Tuesday night.

Some increasing clouds & rapid warm-up to 49-55 is likely Wednesday with strong southerly winds.

Late next week looks warm with spring-like 60s & eventually some showers & t'storms.
