Area forecast discussion, Jul 19, 9:57 PM MST, 2 hours 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
957 PM MST THU JUL 19 2007

.SYNOPSIS...HIGH PRESSURE ALOFT WILL REMAIN NEAR THE FOUR CORNERS.
ADEQUATE MOISTURE IN COMBINATION WITH DAYTIME HEATING WILL PROVIDE
ISOLATED TO SCATTERED THUNDERSTORMS MAINLY DURING THE AFTERNOON AND
EVENING HOURS. ACTIVITY WILL INCREASE INTO THE WEEKEND AS STRONGER
EASTERLY FLOW OCCURS.

&&

.DISCUSSION...A VERY BUSY LATE AFTERNOON AND EVENING WITH CONVECTION
FLARING UP INITIALLY OVER SANTA CRUZ COUNTY WHERE THE STORMS TURNED
SEVERE OVER THE EXTREME SOUTHEAST PORTION OF THE COUNTY. MEANWHILE A
SEVERE STORM DEVELOPED OVER CENTRAL GRAHAM COUNTY NORTHEAST OF
HIGHWAY 70 NEAR THE TOWNS OF PIMA...THATCHER AND SAFFORD. THIS STORM
MOVED ACROSS THOSE AREAS...BUT AS OF NOW WE HAVE NOT RECEIVED GROUND
TRUTH REPORTS TO CONFIRM THAT THIS STORM WAS SEVERE...EVEN THOUGH
RADAR SIGNATURES WERE INDICATING A SEVERE STORM. AS THE EVENING
PROGRESSED THE STORM IN SANTA CRUZ COUNTY PRODUCED 1.5 INCH DIAMETER
HAIL IN PATAGONIA. STORMS THEN BEGAN TO DEVELOP IN COCHISE COUNTY
WITH A LINE EVENTUALLY DEVELOPING FROM SANTA CRUZ COUNTY...ACROSS
EXTREME SOUTHEAST PIMA COUNTY AND WEST CENTRAL COCHISE COUNTY AND
INTO SOUTHWEST GRAHAM COUNTY. THIS LINE THEN MOVED NORTHWEST INTO
EASTERN PIMA COUNTY AND MADE ITS WAY ACROSS THE ENTIRE TUCSON METRO
AREA. THE MAIN IMPACT THESE STORMS HAD ON THE TUCSON AREA WAS
DAMAGING WINDS AND BLOWING DUST REDUCING VISIBILITIES DOWN TO A
QUARTER OF A MILE FOR AREAS FROM TUCSON AND INTO SOUTHEAST PINAL
COUNTY. FOR A COMPLETE LISTING OF DAMAGE REPORTS FROM AROUND THE
AREA REFER TO OUR LATEST LOCAL STORM REPORT (PHXLSRTWC). A FLOOD
ADVISORY CONTINUES ACROSS CENTRAL PIMA COUNTY...INCLUDING THE TOHONO
OODHAM NATION UNTIL 1145 PM MST.

WILL MAKE ADJUSTMENTS TO THE GRIDS AND ZONE FORECASTS TO REFLECT
THE CURRENT RADAR TRENDS.

&&

.FIRE WEATHER...THE DAILY CYCLE OF MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS IS EXPECTED TO CONTINUE INTO THE WEEKEND.
WINDS WILL BE DIURNALLY DRIVEN...WITH AFTERNOON GUSTS UP TO 25 MPH
DUE TO SURFACE HEATING. ADDITIONALLY...ANY THUNDERSTORMS THAT OCCUR
WILL BE CAPABLE OF PRODUCING STRONG...GUSTY AND ERRATIC WINDS.
RELATIVE HUMIDITY VALUES OVERNIGHT WILL BE IN THE 45 TO 75 PERCENT
RANGE...WITH VALUES DROPPING IN THE AFTERNOON HOURS INTO THE 20 TO
30 PERCENT RANGE.

&&

.AVIATION...ISOLD TO SCT TSRA/SHRA ARE EXPECTED ACROSS SOUTHEAST
ARIZONA THROUGH THE REMAINDER OF THIS EVENING. EXPECT SCT-BKN090CB
UNTIL AROUND 06Z BEFORE THE CLOUDS WILL BEGIN TO ERODE WITH MAINLY
SCT120 SCT-BKN250 AFTER MIDNIGHT. AVIATION DISCUSSION NOT UPDATED
FOR TAF AND TWEB AMENDMENTS.

&&

.CLIMATE...THE CONSECUTIVE DAY STREAK OF DAYTIME HIGH TEMPERATURES
OF 100 OR GREATER AT THE TUCSON AIRPORT HAS REACHED 37 DAYS AS OF
TODAY. HAVING HIT 103 AT THE TUCSON INTERNATIONAL AIRPORT...TODAY
QUALIFIES AS DAY 37. DUE TO INCREASED MOISTURE AND THUNDERSTORM
ACTIVITY FRIDAY AND SATURDAY...WE ARE FORECASTING 99 FOR FRIDAY AND
97 FOR SATURDAY SO IT LOOKS LIKE TUCSON WILL FALL JUST SHORT OF
TYING THE ALL-TIME RECORD OF 39 CONSECUTIVE DAYS. IN ANY EVENT...IT
WILL BE ANOTHER HISTORIC RUN OF 100+ TEMPERATURES FOR TUCSON.

TOP 5 LONGEST CONSECUTIVE DAY STREAKS OF HIGHS 100 DEGREES OR BETTER:

1) 39 DAYS IN 2005 (JUNE 14TH TO JULY 22ND)
   39 DAYS IN 1987 (JUNE 7TH TO JULY 15TH)
3) 37 DAYS IN 2007 (JUNE 13TH TO JULY 19TH) ***
4) 33 DAYS IN 2002 (JUNE 13TH TO JULY 15TH)
5) 32 DAYS IN 1942 (JUNE 13TH TO JULY 14TH)
