DISCUSSION
 
 
SHOWERS ARE CURRENTLY WORKING THEIR WAY EASTWARD OFF THE PLATEAU,  
WITH VERY LITTLE IF ANY THUNDER SO FAR TODAY. MODELS DID PLACE A  
BIT OF INSTABILITY OVER THE EASTERN HALF THIS AFTERNOON, BUT CLOUD  
COVER AND THE FRONT MOVING THROUGH HAS WEAKENED THE INSTABILITY  
POTENTIAL. STRONG WINDS OF 10 TO 20 MPH AND GUSTS UP TO AROUND 30  
MPH WILL BE POSSIBLE FOR THE REMAINDER OF THE AFTERNOON, AND AGAIN  
TOMORROW. WITH DRIER CONDITIONS IN PLACE SUNDAY, AND STRONG WINDS  
CONTINUING, MARGINAL FIRE DANGER CONDITIONS MAY BE POSSIBLE,  
ESPECIALLY FOR AREAS THAT HAVE NOT RECEIVED MUCH RAINFALL OVER THE  
PAST DAY OR SO. WITH STRONG WINDS, SOME ENHANCED LOW LEVEL MIXING  
WILL BE POSSIBLE, AND HIGH TEMPS MAY CLIMB INTO THE MID 70S WHICH  
WOULD DROP MIN RH VALUES TO AROUND 20 PERCENT FOR SOME AREAS  
SUNDAY AFTERNOON.  
 
BY MONDAY, MODELS HAVE SUGGESTED A WEAK MIDWEST TROUGH MAY BRING  
SOME LIGHT RAIN CHANCES TO THE MID STATE, BUT SOLUTIONS HAVE NOT  
BEEN CONSISTENT. KEPT RAIN CHANCES OUT OF THE FORECAST FOR NOW,  
BUT TRENDS ARE CONTINUING TO INDICATE SCHC/CHC POPS COULD BE PUT  
IN FOR MONDAY AFTERNOON. MOST OF THE TROUGH ACTIVITY TO START OFF  
THE WEEK WILL BE TO OUR NORTH, AND SHOULD KEEP US DRY ON TUESDAY.  
BY WEDNESDAY AND THURSDAY, A STRONG RIDGE STARTS TO FORM IN THE  
PLAINS, BUT IS QUICKLY WEAKENED BY A DEVELOPING TROUGH LATE  
THURSDAY INTO FRIDAY. TEMPS WONT WARM UP TOO MUCH AS A RESULT, AND  
SOME RAIN CHANCES MAY MOVE BACK IN LATE THURSDAY INTO NEXT  
WEEKEND. STILL NOT TOO IMPRESSED WITH THE SOLUTIONS BETWEEN THE  
GFS AND ECMWF NEXT WEEKEND AS THE GFS HAS ANOTHER MIDWEST TROUGH  
AND THE ECMWF IS MORE ZONAL/WEAK RIDGE, SO NOT PUTTING TOO MUCH  
WEIGHT ON RAIN NEXT WEEKEND.
