..SYNOPSIS
BROADLY CYCLONIC FLOW ALOFT IS CURRENTLY IN PLACE ACROSS MUCH OF THE
CENTRAL AND EASTERN CONUS, ANCHORED BY AN EXPANSIVE UPPER LOW
CENTERED OVER CENTRAL ONTARIO. EARLY-MORNING SATELLITE IMAGERY SHOWS
A PAIR OF SHORTWAVE TROUGHS WITHIN THE WESTERN PERIPHERY OF THIS
CYCLONIC FLOW, WITH THE LEAD WAVE ENTERING THE TX PANHANDLE AND OK
AND THE SECOND WAVE MOVING THROUGH WESTERN WY. BOTH OF THESE
SHORTWAVES ARE FORECAST TO MOVE SOUTHEASTWARD THROUGHOUT THE DAY,
WHILE ANOTHER NOTABLY STRONG SHORTWAVE DROPS SOUTHWARD INTO THE
NORTHERN PLAINS AND UPPER MIDWEST EARLY TOMORROW. EVOLUTION OF THESE
WAVES WILL REINFORCING THE COLD, DRY, AND STABLE AIRMASS ALREADY IN
PLACE, AND NO THUNDERSTORMS ARE EXPECTED.
UPPER RIDGING IS EXPECTED TO BUILD ACROSS MUCH OF THE WESTERN
CONUS/INTERMOUNTAIN WEST TODAY. AS IT DOES, A PAIR OF SHORTWAVE
TROUGHS ARE FORECAST TO MOVE THROUGH BRITISH COLUMBIA AND THE
PACIFIC NORTHWEST. SHOWERS WITH EMBEDDED CONVECTIVE ELEMENTS WILL
ACCOMPANY EACH OF THESE WAVES, BUT ANY CONVECTION SHOULD BE TOO
SHALLOW FOR LIGHTNING PRODUCTION.
