SATELLITE ANALYSIS AND TRENDS...UPPER LOW ROTATING SLOWLY ENEWD OUT
OF THE DESERT SW IS SEEN ON WV IMAGERY CURRENTLY OVER THE AREA WHERE
BORDERS OF S NV/NW AZ/SW UT MEET. S/WV ENERGY IS SEEN ROTATING AROUND
THE S SIDE OF THE UPPER LOW OUT OF SE CA AND INTO NW AZ PROVIDING ENOUGH
INSTABILITY FOR FAIRLY SUBSTANTIAL TSTORMS. PLOT OF MOST RECENT STLT
WINDS SHOWS MID LVL FLOW DROPPING IN FROM THE NW BEHIND THE UPPER LOW
INTO WRN SAN BERNARDINO COUNTY LIFTING OUT FROM THE SW AS THE FLOW ENTERS
MOHAVE COUNTY IN AZ. SFC WINDS SHOW A SIMILAR PATTERN THOUGH MUCH LESS
DEFINED AND MORE IN AN W-E/NE PATTERN. HAVE A LITTLE CONCERN FOR PARTS
OF NW AZ THAT HAVE LOWER FFG AS CELLS APPEAR TO BE GOING TO TRAIN ACROSS
S MOHAVE/N YAVAPAI/W AND CENTRAL COCONINO OVER THE NEXT 2-3 HRS. UPSLOPE
FLOW WILL INCREASE RAINRATES AS CELLS MOVE INTO THE MTNS OF NW AZ. GOES
SOUNDER INDICATES MAX PW VALUES AROUND 0.5" AND 00Z SFC OBS DO SHOW MID
40S DEWPTS AT KIFP AND KEED SO THERE IS A LITTLE BIT OF MOISTURE FOR THE
CELLS TO WORK WITH BUT NOT A LOT. CELLS ARE WARM TOP AT -44C BUT MAY BE
CAPABLE OF PRODUCING UP TO 0.5"/HR RATES..ESPECIALLY ON THE SERN SIDE OF
MTN RANGES. FLOW AROUND UPPER LOW SHOULD BE ABLE TO PULL SEVERAL ROUNDS
OF STORMS OVER ABOVE MENTIONED COUNTIES AND SO WILL HAVE TO BE WATCHED
CLOSELY FOR TRAINING. WILL CONTINUE TO MONITOR.
