HIGH PRESSURE OVER THE NORTHERN PLAINS AND AN UPPER RIDGE BUILDING
OVER THE ROCKIES WILL BRING HOT AND DRY WEATHER TO THE TREASURE
STATE OVER THE NEXT FEW DAYS. AS THE RIDGE BUILDS TEMPERATURES
WILL PUSH INTO THE 90S, PEAKING ON WEDNESDAY.
A SHORTWAVE PUSHING THROUGH THE RIDGE WILL DEVELOP A LOW PRESSURE
SYSTEM OVER ALBERTA ON WEDNESDAY. A LEE TROF/DRY LINE FEATURE WILL
EXTEND SOUTH FROM THIS LOW INTO MONTANA, AND WILL PROVIDE A
FOCUS FOR A FEW THUNDERSTORMS ON WEDNESDAY AFTERNOON OR EVENING AS
IT LIFTS EAST.
TEMPERATURES COOL SLIGHTLY ON THURSDAY WITH A COLD FRONT DIPPING
SOUTH OF THE CANADIAN BORDER AND THE FLATTENING OF THE UPPER
RIDGE. WINDIER CONDITIONS ARE ALSO EXPECTED.
RIDGE REBOUNDS FOR THE END OF THE WEEK, ALTHOUGH NOT AS STRONGLY,
FOR MORE HOT AND DRY WEATHER INTO THE WEEKEND. EBERT
