VALID 241200Z - 251200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE NOT EXPECTED ACROSS THE UNITED STATES.
.. DISCUSSION
THE UPPER-AIR PATTERN WILL DEAMPLIFY SOMEWHAT ON TUESDAY AS A
MID-LEVEL TROUGH MOVING ONSHORE IN THE PACIFIC NORTHWEST HELPS BREAK
DOWN THE WESTERN RIDGE. THE RESULT SHOULD BE BROAD NORTHWEST FLOW
ACROSS MUCH OF THE US. AT THE SURFACE, IN RESPONSE TO THIS NORTHWEST
FLOW, TROUGHING WILL DEVELOP IN THE LEE OF NEARLY THE ENTIRETY OF
THE US ROCKY MOUNTAINS. SOUTHERLY WINDS TO THE EAST OF THIS TROUGH
WILL BEGIN DRAWING MOISTURE NORTHWARD INTO THE SOUTHERN PLAINS.
GIVEN THE LIMITED MOISTURE ACROSS THE CENTRAL AND EASTERN US, AND
THE SATURATED, INSTABILITY DEPRIVED FORECAST SOUNDINGS ASSOCIATED
WITH THE EXPECTED MOIST, ONSHORE/UPSLOPE FLOW ACROSS CALIFORNIA,
THUNDERSTORMS ARE CURRENTLY NOT ANTICIPATED ON TUESDAY.
