March Medium/ Long Range

With the Western US ridge really overperforming today (Portland almost hit 80*), Models really trended warmer in the medium range for the US, with that being initialized. Really amped this +NAO/+EPO pattern, maybe something near 90* around here isn't so far away.  Apr 4-7 looks warm, if not hot.

I'm hyped.

I could care less for 90 since summer lasts here until the end of October, 8 months from now. Rainfall and drought feedback will play a role here this summer despite some modeling going with the core of the heat in the Midwest and Plains.

It's wild how the Richmond area has been a magnetic for precip for the past year. That area has a surplus of rain. 

You're dwelling too much on Richmond.  In December of 2024, Richmond was in moderate drought.

Rainfall deficits have been a problem in the MA for 5 years now.

The same anomaly contributes to the snow drought.

I guess you're right come to think about it. The drought has been kinda morphing around the MA for a long time. My area got swamped for several years while the Blue Ridge droughted out.

We need a 2018.  My IG is set to private, but I made a post there showing June 2018 vs December 2017 at Great Falls.  The difference was ridiculous.  I think 2017 was wet too, but more so in the summer.  Definitely mosquito, spider, and gnat type of weather.  In a weird way, I miss it lol.

It is not just the GFS that has wacky runs at range.  Latest WB 18Z AI....

This goes for everyone.. if the model is showing snow in the long range:
1) Look at the 500mb index patterns

- Is the NAO negative?

- Is the PNA positive?

- Is the EPO negative?

If not, don't expect troughs. This kind of hit me when PSUhoffman said 10% chance it verifies.. in reality, it's about 1-2%. Unless the NAO is negative, ensemble mean is showing a trough over the east, etc. 

For your map, I'd say it's 1% chance of verifying.  It hit 82F in Portland today.

If anything this should translate into rainfall potential, however, weeks 3 to 4 look drier

The next 7 days don't look very promising for drought relief in the areas that need it most. Maybe an inch? GEFS looks similar.

Knowing the pattern since last summer this will get walked back to about 5-25% of what's on this map by Monday.

Exactly. Very discouraging for agriculture and for the water tables. Soil moisture levels continue to decline and will do so even more the next couple days with the warmer temperatures.
