Very moist / tropical airmass from Texas into the Southeast fueling thunderstorms and heavy downpours.

\"\"

On the West Coast, a rather chilly air mass from the Pacific Northwest is sinking southward behind a rather potent mid-level trough of low pressure leading to showers across northern California.

\"\"

Pattern Shifted \u2014 Boatloads of Rainfall Over the Past 7-days

\"\"

Compared to climatology \u2014 shows the very welcome rain for some drought relief.

\"\"

ECMWF 18z | Forecast 6-days of Precipitable Water (my favorite parameter!)

\"\"

A lot of red (> 2\u201d PWAT) showing up out of the Gulf of Mexico = deep tropical moisture plume accumulates over the next 6-days+

Troughs on either side of the Omega block = dry Canadian or Arctic air

Omega Block Pattern | Next 6-days of troughs and ridges

\"\"

The blocking pattern ridge is centered over Hudson Bay Canada with the Northeast really unlucky again with persistent troughing. The Western U.S. recovers from a cut-off low with a warming trend.

Temperature Anomaly Next 6-days \u2014 into Monday Afternoon

\"\"

Cooler than normal air across the Northeast \u2026 comfortable to start June in NYC and D.C with mainly mid-70s.

\"\"
\"\"

Quick Trip Across the Pond to \u201cBaking Western Europe and the United Kingdom\u201d

\"\"

Yet another day in the 80s and 90s around the English Channel with London and Paris in the 80s on Wednesday \u2026 maybe a bit hotter on Thursday.

Then, back to the 50s and 60s \u2014 more typical Atlantic fresh air in London

\"\"

Similar story for Paris \u2014 90s for Saturday and then back to typical comfortable early-June 60s and 70s.

\"\"

Precipitation Next 10-days | Blend of Models (v5.0)

\"\"

Very wet pattern continues across the Southeast \u2014 with focus on Florida!

High Temperatures Next 9-days until Thursday, June 4th

\"\"

70s and 80s dominate into early June with only minimal population in 90s. No heat dome across the Eastern U.S.

ECMWF 18z | Precipitation Type + MSLP | Next 6-days

\"\"

Not seeing a break in the daily showers from Texas to the Southeast with the southerly / moist flow = a lot MORE rain

ECMWF Flagship Ensemble Temperature Outlook

Temperature Anomaly | Next 15-days | ECMWF EPS 12z Ensemble Mean

\"\"

The Omega block warms up Canada finally after a very long winter \u2026 and the moisture / clouds from Texas into Southeast \u2014> keep things cooler.

Week #1 | Temperature Anomaly | May 26 - June 2

\"\"

Week #2 | Temperature Anomaly | June 2 - June 8

\"\"

Integrated Vapor Transport | Next 10-days

\"\"

Persistent pattern continues for the south from Texas into the Southeast with strong southerly flow around the Bermuda / subtropical high / ridge anchored off the Eastern U.S. \u2014> boatloads of moisture/rainfall for Texas into the Lower Mississippi River Valley and Florida.

Watching longer range into next week for a potential tropical system in the Gulf of Mexico.

ECMWF AIFS-Single 18z | 500 mb Height Anomaly Next 10-days

\"\"

Blocking pattern sets up with the ridge axis centered along Hudson Bay and Ontario with troughs on either side \u2026 Western U.S. and Northeast cooler than normal, and allow the moisture flow out of the Gulf to sustain the ridge on the backside.

Europe Upper-Level Pattern

\"\"

The ridge breaks down by this weekend \u2014 and much cooler air arrives from the Atlantic and Iceland/Greenland for Europe.
