All Activity

Looks like we finally see a breakdown of this heat ridge this weekend. We go from the 80s to highs possibly in the 50s with possibly more frost. Looking further out we may finally see a more moist pattern setup over the East also.

Wednesday's convective outlook. Slight risk sneaking into north and west central pennsylvania. https://www.spc.noaa.gov/products/outlook/day2otlk.html

First slight risk!

Man, what a beaut out by Guam.

The eyewall should start hitting land within the next two hours or so. This is one dangerous storm. I wonder how good typhoon preparedness is in the Northern Mariana Islands, especially when it comes to a direct hit?

The final strat. warming occurred on April 9th, 13 days earlier than average: @snowman19

Same here My landlord has the heat on

Does anyone disagree with what Chris Martz says here? He says that a record hot W US March would still have occurred had there been no GW because that elevates the starting temperature by no more than about 3F whereas records were smashed by 10-20F. So, this heat wave would still have been unprecedented in the records in scope. It just wouldn’t have been quite as hot, which is consistent with my thinking. I essentially already had said all of this ITT on April 3rd at this link: I’d like to add that the extreme cold over AK/W Canada and the record strong March +NAO were likely all associated with each other. Also, note that on a seasonal basis, cold/warm E US winters are often associated with warm/cold W US winters due to the opposite reaction idea. Also, a cold US winter is often associated with a warm Canadian winter. The W heat was caused by a record strong upper level ridge over the W US. But the ridge, itself, was associated with an atmospheric Rossby wave. Because of La Niña, there was low frequency convection over the W and C tropical Pacific. That caused a cyclonic circ. (deep low) to form over Hawaii. Downstream of that, a record strong ridge was pumped up over the W US:

still have my heater on as i feel cold..

Impressive light show in Traverse City. More lightning tonight than I might have seen in an entire season down in Macomb.

Definitely about as thread the needle as you can get. Fortunately, the bulk of the activity was just south of the densely populated suburbs in KC... DFW has conditional setups like this all the time during severe weather season, but thus far, its cap of steel remains undefeated.

I have pictures of the that in the woods. Near full leaf out and snow sticking on leaves.

I find it funny how those freak May snowfalls (in 2002 and 2020) happened after winters that were very warm and pretty much snowless.

Sinlaku's eyewall looks like it's coming right at Saipan and Tinian. I'm not sure if Extreme Wind Warnings can be issued for the Northern Mariana Islands (I know they can, and have, been issued for Guam), but the situation appears as if it would warrant an EWW once the eyewall gets closer.

for tomorrow, SPC has put up a 10% tornado risk including northern Illinois and Chicago, and also 30% hail

I may not be north enough to be considered far but I'm furious this rainy week will dim my spring jollies. The lack of sun is killing the mood. I don't buy this, but TWN doesn't give me a partly sunny day until Apr 21!!! With the last 3 weeks being mostly dark gloom, many of us near the lakes would go stark raving mad with a wem that bad.

New NAM is a little slower with it so we salvage a nice day on Wed but with how cold the waters are it won't take much for one to surge SW.

I see that COD's text products are broken..again.

The most historic part of the night may be how there was a strong tornado (KC) in a spot that this morning didn't even have a general thunderstorm risk area!! I have no memory of this happening before.
