THROUGH FRIDAY, WITH CHANCES FOR SHOWERS AND THUNDERSTORMS. DRY
CONDITIONS RETURN FOR THIS WEEKEND.
DISCUSSION
A TROUGH LOCATED OVER THE GREAT BASIN WILL PUSH
SOUTHWARD AND CROSS THROUGH THE STATE TOWARDS THE END OF THE WEEK.
THE TROUGH DIGS SOUTHWARD AND WITH A HIGH RESIDING OFF TO OUR EAST,
THE PRESSURE GRADIENT WILL TIGHTEN UP APPRECIABLY, BRINGING STRONG
SOUTH TO SOUTHWEST WINDS TO THE REGION. EXPECT WINDS AROUND 15-25
MPH WITH GUSTS 35-45 MPH TODAY, DECREASING SLIGHTLY ON THURSDAY.
A WIND ADVISORY REMAINS IN EFFECT THROUGH 7PM THIS EVENING FOR
MUCH OF THE AREA.
MOISTURE WILL START TO INCREASE IN THE DEVELOPING SOUTHERLY FLOW.
HOWEVER, THE BEST MOISTURE ADVECTION WILL BE INTO EASTERN ARIZONA,
WITH MUCH OF THE SHOWER AND STORM DEVELOPMENT EAST OF PAGE TO PAYSON
LINE. THE MOISTURE HANGS AROUND THROUGH FRIDAY BEFORE THE TROUGH
PUSHES TO THE EAST, DRAGGING ANY LINGERING CHANCES OF PRECIPITATION
WITH IT. BEST CHANCES WILL GENERALLY BE ACROSS THE EASTERN HALF OF
THE FORECAST AREA.
AS THE TROUGH EXITS TO THE EAST AT THE END OF THE WEEK, WE SEE A
MORE WESTERLY FLOW ARRIVE AND WITH THAT WE DRY OUT AND SHOULD SEE
TEMPERATURES START TO WARM SLIGHTLY.
