.SHORT TERM...VALID FOR TUE AND WED...
SHORT TERM MODELS IN GOOD AGREEMENT ON THE TIMING AND DETAILS OF
A SHORT WAVE MOVING TOWARD US FROM IDAHO THIS AFTERNOON...WHICH
IS EASILY CONFIRMED FROM SATELLITE AND RADAR IMAGERY. THIS
MONSOONAL IMPULSE WILL CRASH THROUGH THE RIDGE ALOFT THIS EVENING
SPREADING ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ACROSS
THE W/SW PORTIONS OF OUR COUNTY WARNING AREA. A FEW STORMS MAY
REMAIN INTACT OVERNIGHT AS THIS FEATURE SHIFTS EAST. SO WILL
CONTINUE SLIGHT CHANCE POPS OVERNIGHT THROUGH THE PLAINS. I AM
NOT EXPECTING WIDESPREAD FREQUENT DRY LIGHTNING AS INSTABILITY IS
LOW TO MODERATE AND FORCING DOES NOT SEEM THAT STRONG. BUT ANY
LIGHTNING WILL BE A PROBLEM WITH A MIX OF GARDEN VARIETY WET/DRY
THUNDERSTORMS DUE TO DRY FUELS/CONDITIONS. THUS...RED FLAG WILL
CONTINUE FOR INCREASED THUNDERSTORM ACTIVITY AND POTENTIAL FOR
DRY LIGHTNING/LOW HUMIDITY IN PLACE THROUGH MIDNIGHT.
DRY NORTHWEST FLOW WILL DEVELOP TUESDAY BEHIND TONIGHTS WEATHER
FEATURE. ANY THUNDERSTORM ACTIVITY TUESDAY WILL BE LIMITED TO THE
EASTERN BORDER COUNTIES WHERE SURFACE CONVERGENCE ASSOCIATED WITH
THE EXITING SYSTEM DEVELOPS. WE HAVE BEEN CONCERNED ABOUT FIRE
WEATHER CONDITIONS ON TUESDAY AS BRISK NORTHWEST WINDS WILL
COMBINE WITH LOW RELATIVE HUMIDITY IN THE AFTERNOON PRODUCING
SIGNIFICANT FIRE WEATHER CONDITIONS. HOWEVER...WINDS MAY NOT BE
WIDESPREAD AND WILL BE JUST BETTER THAN MARGINAL IN MANY CASES.
IN ADDITION...I DO NOT WANT TO CONFUSE CURRENT FIRE WEATHER
HIGHLIGHTS WITH TOMORROW WHICH WILL BE FOR DIFFERENT WEATHER
ATTRIBUTES AND AFFECT A LARGER PORTION OF THE EAST. WE WILL HOLD
OFF ON ADDITIONAL FIRE WEATEHR HIGHLIGHTS AT LEAST UNTIL THE
CURRENT HIGHLIGHT IS CANCELLED AND EVALUATE WIND EXPECTATIONS FOR
TUESDAY AT THAT TIME.
THE RIDGE WILL REBUILD WEDNESDAY WITH ANOTHER MONSOONAL TYPE WAVE
IN LINE TO IMPACT THE REGION BY WEDNESDAY EVENING AS IT MOVES UP
FROM NEVADA AND IDAHO IN THE SOUTHWEST FLOW. ONCE AGAIN...DRY LOW
LEVELS ARE EXPECTED WITH INVERTED V SOUNDINGS. SO HIGH BASED
THUNDERSTORMS AND THE POTENTIAL FOR DRY LIGHTNING WILL BE A
CONCERN. HOT TEMPERATURES CAN BE EXPECTED WEDNESDAY WITH 500MB
HEIGHTS BETWEEN 591 DM AND 594 DM IN OUR AREA. BT

IMPACT THE CWA LATE FRIDAY INTO EARLY SATURDAY. AN UPPER-LEVEL
TROUGH WILL DEVELOP OVER THE PACIFIC NORTHWEST BY LATE IN THE
