Mammatus Clouds from May 3, 2012

This picture shows mammatus clouds from a strong storm cell in Chicago, IL on May 3rd, 2012. I will be releasing more pictures later today.

Thanks for the photos. I love snapshooting the backshears and mammati as well.

Tomorrow may be interesting for NE and IA with their high CAPEs of 2500-3500. Earlier it was worse at 5000 kj! The scenario hasn't changed however. The SPC said NE may have supercell domination. They also said there could be tornadoes as the LLJ increases. For IA, an MCS is likely capable of large hail, damaging winds, and again tornadoes. This could be a near-MDT or MDT threat. Take care!

I wonder when this would dip back down to KS since May is worse for KS.

Hello. I have a question for you. What would be the best combination of ENSO Conditions, the NAO, the AO, etc., for the Great Lakes region to see the most snow next winter. Thanks.

Anonymous: Considering the jet stream cannot stay zonal for a long time, the jet stream should shift back south somewhat soon.

WinterStorm: A negative AO, La Nina are key pieces. Rather than the NAO, the PNA bears watching. A positive PNA encourages Midwest storms.

That's not good. It looks like we are going to have an El Nino this year, so how would that effect the storm pattern for us?

Andrew said...

Well, some El Ninos can be good, but considering this will be a weak one, a slightly below average precipitation season is within the realm of possibility.

Just a thought... the low sunspot cycle encourages a -NAO/AO= cooler than average temps for the Great Lakes region and East Coast. Snow ratios would likely be higher than normal so there is a wildcard for above average snow. Cooler than normal temps should dominate east of the Mississippi. The picture is great Andrew. Thanks for posting.

I would just like to know where exactly you think the severe weather threat will be for sunday. The SPC is showing it to be from the Arklatex region and on up into southern ia/nestrn missouri. But the weather channel is showing it from Minneapolis down into Oklahoma City, so just wondering about your thoughts on that.
Thanks.

ERN WX: That is very true. It may not have a significant effect, but that is true.

Storm-Chaser Wx: As of now, it is looking like the Lower Great Lakes, Midwest into the southern Plains appear to be affected.
