While it may be warm now from the Mississippi Valley on east, don’t get use to it. With the PNA going positive and both NAO/AO going negative, this pattern takes the mean trough east while riding builds over the West.

By this weekend, it will be much cooler in the East. Remember the QPF I showed you in the previous post. Look at where the focus of rains is over the next 7 days!

It stays drier further west and this really ties in not only with my May idea for the US with warmer, drier in the West, cooler/wetter in the East, but this pattern is seeding the upcoming summer.

Here’s the 6-10 day outlook

6-10 day precip, no surprise really!

April 24-30th off CPC.

These suggest April ends cooler/wetter than normal in East, warmer, drier in West to start May and should continue that way through much of the month.

Here’s the CFSv2 for May..

Here’s the drought monitor. Guess where the mean ridge sets up this summer? I recon anywhere from the Great Basin to NW Texas.
