Area forecast discussion, May 12, 7:04 PM PST, 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WA 804 PM PDT SAT MAY 12 2007 .SYNOPSIS...A LOW PRESSURE SYSTEM WILL SWING THROUGH THE NORTHWEST TONIGHT AND SUNDAY BRINGING SCATTERED SHOWERS AND THUNDERSTORMS TO THE REGION. THIS WILL RESULT IN MOSTLY CLOUDY AND COOLER CONDITIONS ON SUNDAY. HIGH PRESSURE WILL RETURN ON MONDAY...WITH CLEARING SKIES AND TEMPERATURES WARMING THROUGH MID WEEK. && .DISCUSSION... THE UPPER LEVEL LOW REMAINS ALMOST STATIONARY JUST OFF THE SOUTHWEST WASHINGTON COAST. MOISTURE AND WEAK DISTURBANCES MOVING THROUGH THE LOW ARE KICKING OFF A LINE OF CONVECTION MOVING NORTH THROUGH THE FORECAST AREA THIS EVENING. A FEW EMBEDDED THUNDERSTORMS ARE ALSO POPPING UP. THE BEST INSTABILITY IS ACROSS THE EXTREME EASTERN ZONES AND AT THE TIME THE THUNDERSTORMS HAVE BEEN DEVELOPING OVER THE NORTHERN BLUE MOUNTAINS AND MOVING NORTH ACROSS THE PALOUSE AND INTO THE SPOKANE AREA. 00Z SOUNDINGS INDICATE AN INVERTED V PROFILE BELOW ABOUT 10K FEET WITH A HABOOB NOSE AT ABOUT 625MB. KOTX .5 VELOCITY DATA INDICATES SOME 25-35KT GUSTS MOVING NORTH WITH THE OUTFLOW BOUNDARY. AS SUCH EXPECT SOME SHORT TERM GUSTY WINDS JUST AHEAD AND WITH THE THUNDERSTORMS. AS THIS TIME DO NOT ANTICIPATE WINDS REACHING SEVERE BUT BLOWING DUST COULD POSE LOCALIZED VISIBILITY CHALLENGES. OTERWISE MAINLY SHOWERS ACROSS THE WESTERN ZONES. AS SUCH HAVE BUMPED UP THE POPS SLIGHTLY FOR THIS EVENING ACROSS THE FORECAST AREA. WHILE I KEPT SCATTERED THUNDERSTORMS ACROSS THE EASTERN ZONES FOR THE NEXT FEW HOURS...DECREASED THE POSSIBLITY FROM THE BASIN WESTWARD INTO THE EAST SLOPES OF THE CASCADES. EXPECT THE SHOWERS TO CONTINUE WELL INTO THE EVENING. FIRST LOOK AT THE 00Z MODLES INDICATES THE ATMOSPHERE SHOULD STABILIZE AND THE THREAT OF THUNDERSTORMS SHOULD BE ON THE DECLINE OVER NIGHT. IN ADDITION A FEW TWEAKS WERE MADE TO MIN TEMPERATURES...BUT THESE WERE MINOR. /TOBIN && && .PRELIMINARY POINT TEMPS/POPS...
