Spring takes a backseat once again ... Dr. Dewpoint article

[Stormsfury]

These backdoor cold fronts are something else ... An article on intellicast (Dr. Dewpoint) is very, very interesting ... about this past winter season and snowcover ... from Joe D'Aleo... basically, with the record snow cover in the Northern Hemisphere, winter and these unusually cold and strong high pressure systems from Canada will NOT take a backseat and YET both seasons continue to fight it out ... which may be subsequently reducing the amount of severe weather reports versus average thus far this season with some minor exceptions.

i thought this clash of weather would increase the instability causing more storms...why the difference?

The problem, JQ, is actually explained very well on another thread on WWBB ... in which I also posted on as well ... and also the best reason was posted by HM on yet another thread.

MANY MANY factors play a role in severe wx season. Not just the state of ENSO, QBO, SUN .... but the duration of each. The SOIL moisture content is important. The SSTA in the gulf are important. The general overall pattern. Climatologically, El Nino-east springs have LESS overall tornadic activity than any other combo. 94' speaks for itself. However, climatologically, dont expect severe wx to get to midwest/northern USA until at least mid may. I am sure there are graphics out there, it generally follows the mean JET position for a given period of time.

AS or this year, EL NINO has delievered several STJ s/w .... we have helped to keep moisture return to the following systems weaker. We are also lacking significant amplification, despite the closed lows moving across. EXPECT things to be delayed more this year than normal because of the extensive snow cover/cold in Canada. Read the intellicast article, it beat the late 70s!!

Here's another one for Closed ULL's. It's called Question on Vertically Stacked Low ...

I agree all the way Stormsfury ! This was my feeling of agreement too - the very cold air and record snow in Canada will tend to reduce or surpress the overall severe weather activity southward................

does look like if anything so far this spring, we've seen more cold and snow reports rather than severe weather and tornadoes.

Wonder if this years Hurricane season will make up the difference??
