DISCUSSION
 
 
ANOTHER POTENT SYSTEM STEWING OFF THE PACIFIC COAST WILL BEGIN TO  
INFLUENCE THE REGION TONIGHT. EXPECT UPPER LEVEL WINDS TO INCREASE  
AND SHIFT TO THE SOUTHWEST, AS THE STORM MOVES INLAND. BREEZY  
CONDITIONS WILL PERSIST MONDAY, ALONG WITH SEASONABLY WARM TEMPS. A  
COLD FRONT WILL JUST BE ON OUR DOORSTEP MONDAY EVENING AND PUSH ACROSS  
THE AREA WEST TO EAST OVERNIGHT. EXPECT WINDS OVER EASTERN UTAH AND  
FAR WESTERN COLORADO TO MAXIMIZE IN CONJUNCTION WITH THE FRONTAL  
PASSAGE, SUCH THAT MAX GUSTS MAY OCCUR BETWEEN 3 AND 6 AM. WIDESPREAD  
PRECIP FOLLOWS SUIT, WITH RAIN FALLING MAINLY BELOW 10,000FT UNTIL  
COLD AIR ARRIVES TUESDAY AFTERNOON. A DRYING AND WARMING PATTERN RETURNS  
THURSDAY.  
 
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS  
OR THUNDERSTORMS...
