US Extended Forecast thru Jul 31

At This Point, All The Global Numerical Guidance Has Resolved The Next High-Amplitude Meridional Event During This Anomalous Month Of July, So Solution Differences Are Well Below Average.

Much Of The Agreement Owes To The Stability Of The Upcoming Positive-Phase Pacific-North-American Oscillation. The Longwave Train From The Eastern Pacific To The Western Atlantic Covers Enough Latitude To Preclude The Normal Issues Of Splitting.

Furthermore, The Large, Looping Meridional Waves Extend Into Europe And Asia, Adding An Additional Dimension Of Stability.

The Models Are Indicating Standardized Anomalies Of At Least -3.0 At 500mb Between The Ohio And Tennessee Rivers Mid Period.

The Sensible Weather Anomalies Should Show Up Pointedly Across The Southern High Plains Into The Arklatex, Where Daytime Highs Are Likely To Run Far Below Normal In The Overrunning Zone North Of The Polar Front--Much Like The Event About A Week Ago.

Also Like The Event From Mid Month, The Far West Looks Scorching Hot, With Temperatures Once Again Likely To Reach Or Exceed The Century Mark In Eastern Washington And The Adjacent Lowlands Of Idaho.

Additionally, The Monsoon Should Send Enough Mid-Level Moisture Northward To Fuel High-Based Thunderstorms Throughout Much Of The Parched Far West--A Critical Concern For Wildland Fires.
