3/18: Monday Evening BLOG

1st Off...I want to show you what our 6-10 Day Temperature/Precipitation Outlook is looking like.

<  THIS is showing the Temperature Outlook and now how WY is slightly cooler of 33-40% below Normal, BUT nothing like East of the Mississippi River.

Looking like the Ohio Valley and Mid-South is going to suffer that Trough much longer...

However, I do think Seasonal Temperatures are okay during this time.

< PRECIP outlook for next 6-10 Days.  Much of WY will stay below Average..about 40% Below Average...




THAT Being Said...looks like our next week will stay Dry/Cool..but our next round of Snow could potentially arrive by Thursday in Central WY.









THURSDAY'S Snow Chances..

1st, here is the NAM from Tonight's Model Run:

--A 1004 Low is poised to develop in SE WY and could bring 'some' upslope potential for Central WY, including Casper and Buffalo as we get to Noon Thursday through Thursday Evening.

This didn't look quite as impressive from this mornings run, but it could change. 

At this time, I feel the Snowys/Sierra Madre's could be in the better spot for better Snow Amounts.



2nd..here the GFS from Tonight's Run

-- HERE, a 'Broad' 1000 LOW could slide in for Central WY by 6PM Thursday.

What concerns me is the SANDWICH EFFECT.

Whats That??
You have 2 Streams of Moisture into WY..
1) First wave slides into West of the Divide and splits into the Bighorns/Southern MT.

2) A Southern Stream slides along I-80 in the Sierra's/Snowy's.  THIS is what its shaping up to do so far.  

CENTRAL WY???...Well with our Humidity being quite dry..it'll take a while to get snow to 'moisten' and 'condense' so as the Front passes through the Evening...not enough Snow is potential to accumulate. THUS, this is what I call the 'Sandwich Effect'

SO HOW MUCH Could we see Out of This?

The New WPC (Weather Prediction Center) is showing the chances of 4" or GREATER for this Thursday's Storm.

What I mentioned for Central WY correlates to the GFS...West of the Divide can likely see up to 8" and then the Snow could spill over 4" for the Bighorns and Sierras/Snowys.

AS FOR Casper/Central WY...The 'Sandwich Effect' is showing up.

Will keep you updated!~
