EVENT...TSTMS RAPIDLY DEVELOPING OVER NW QUARTER OF AZ
.
SATELLITE ANALYSIS AND TRENDS...TSTMS HAVE BEGUN TO DEVELOP OVER
YAVAPAI/CONCONINO/MOHAVE COUNTIES..WITH THE COLDEST TOP AND MOST NUMEROUS
ONES ATTM OVER MOHAVE COUNTY. OBJECTIVE ANALYSIS SHOWS SE-NW ZONE OF
MODERATE SFC CONVERGENCE EXTENDS FM CENTRAL AZ NWWD ACRS SW UT INTO
CENTRAL NV. THIS COINCIDES WITH INCRG INSTABILITY AND HIGH PW'S PER
GOES SOUNDER IMAGERY..AS WELL AS LL THETA-E RIDGE AXIS. LL AS WELL AS
UPPER LEVEL WINDS ARE ON THE LIGHT SIDE..ALLOWING FOR SLOW MOVEMENT OF
TSTMS. UPPR LEVEL WINDS..PER GOES STLT..ARE SERLY AROUND 15-20KTS..WHICH
SUGGEST MOVEMENT OF CELLS TWD THE NW..ALBEIT ON THE SLOW SIDE. WITH
THE INCR IN TSTM NUMBER..SLOW MOVEMENT AND MERGERS..VERY HVY RAINFALL
IS LIKELY TO OCCUR OVER NUMEROUS LOCATIONS OVER NW QUARTER OF AZ. IN
ADDITION TO WHAT MAY DEVELOP OVER NV AND UT..WOULD EXPECT SOME OF THE
AZ TSTM ACTIVITY TO SPREAD INTO THOSE AREAS AS WELL. STLT TRENDS AND
MOISTURE PARAMETERS SUGGEST RAINFALL OF 1-2" IN AN HRS TIME WILL BE
COMMON. SLOW MOVG STMS AND CELL MERGERS CAN PRODUCE OVER 2" IN AN HOUR
OR LESS..ESP/MAINLY OVER AZ.
