EVENT...MERGER OVER NE AZ/NW NM BORDER..SLOW MOVING CELLS IN E CENTRAL AZ
.
SATELLITE ANALYSIS AND TRENDS...RECENT IR IMAGERY SHOWS SEVERAL AREAS OF
CONCERN FOR LOCALLY HVY RAINS IN AZ/NM. ONE IS OVER THE AZ/NM BORDER IN
NE APACHE/NW MCKINLEY/SW SAN JUAN COUNTIES WHERE A MERGER JUST OCCURRED
BETWEEN 1900-1915Z. SMALL CELLS ARE ALSO GROWING OVER THE REST OF NRN
APACHE AND APPEAR AS THOUGH ADDTL MERGERS MAY OCCUR OVER THAT COUNTY AS
THE GROUP OF CELLS VERY SLOWLY PROGRESSES WWD WITH THE OUTFLOW. PART OF
THE GROUP OF CELLS IS HANGING BACK THOUGH INTO THE NM COUNTIES PRODUCING
LOCALLY HVY RAINS. ONE HR OBSERVATION FROM KRQE WAS 0.4" AND THE MERGER
OCCURRED JUST N OF THERE AT THE SW CORNER OF SAN JUAN/NW CORNER OF
MCKINLEY COUNTIES. STLT ESTIMATES HAD SHOWN RAIN RATES OF UP TO 1.1"/HR
DURING THE MERGER AND 0.4" AMOUNTS ENDING 1916Z BUT ARE LIKELY UNDERDONE
BY 0.3-0.5" AT THE POINT OF THE MERGER.
.
OTHER AREA TO WATCH IS OVER S APACHE/S NAVAJO/GILA/GRAHAM/E PINAL
COUNTIES WHERE COLD TOP CELLS CONTINUE TO DVLP AND MERGERS WILL BE
POSSIBLE DURING THE NEXT 2-4 HRS AS NEW CELLS FILL IN BETWEEN THOSE
ALREADY PRESENT. ENTIRE NM/AZ BORDER AREA IS WITHIN STRONG THETA-E
AXIS WITH PW'S OF 1.4-1.6" OF SW NM/SE AND E CENTRAL AZ..LESSENING A
LITTLE TO 1-1.25" OVER THE NRN PART OF THE STATE BORDER INTO SW CO/SE
UT. UPPER HIGH IS BECOMING MORE TIGHTLY COMPACTED BY JET OVER CA/LOW
OVER W CENTRAL TX WHICH WILL ALLOW FOR S/WV'S TO HAVE MORE IMPACT AS THEY
PROGRESS AROUND THE UPPER FEATURE. DIURNAL HEATING HAS BEEN ENOUGH THUS
FAR AND CELL MOVEMENT IS SLOW WITH LIGHT WINDS WHICH WILL MAKE FOR HVY
RAIN PRODUCERS. 1 HR AUTOMATED ESTIMATES ENDING 1930Z SHOW 1.1" MAX OVER
S NAVAJO COUNTY. SEE WEB ADDRESS FOR GRAPHIC IN ABOUT 10 MIN.
