NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
900 PM MDT Thursday Jul 2 2015 

Discussion...weak convection /isolated showers/ near the or/Nevada 
border has ended. Therefore...will be updating to remove mention 
of isolated showers and thunderstorms. Moisture near the Nevada 
border may creep a little further north on Friday for a slight 
chance of afternoon showers and thunderstorms in portions of southeast 
Oregon and SW Idaho just north of the Nevada border. Otherwise... 
expect hot and dry conditions with high temperatures on par with 


Aviation...VFR. Areas of smoke locally reducing visibilities in 
the kbno and kbke areas. Surface winds...west to northwest 10-15 
kts diminishing to less than 10 kts by 06z. Winds aloft...west to 
northwest 10-20 kts up through 10k feet mean sea level. 


Previous discussion... 
short term...continued hot through Saturday with isolated afternoon/ 
evening thunderstorms near the Nevada border...but a little farther 
north Saturday. Dry elsewhere. Little change in the synoptic 
pattern with upper high still over the Great Basin...but a slight 
difference in the far north where upper winds will turn to west-northwest 
and bring slight cooling. For Boise...Saturday should reach 100f 
and tie their record for most consecutive days with nine. 

Long term...Saturday night and Sunday...upper trough moving across 
western Canada will push the Great Basin high far enough south to cool 
temperatures about 5 degrees Sunday and finally keep maximum temperatures below 100f... 
except in the lowest valleys and near Bruneau and Grandview in 
Idaho. Thunderstorms in southern-most zones Saturday evening may send 
outflow winds northward into the Treasure and Magic Valleys. Clouds will 
keep temperatures warm Saturday night. 
Sunday night through Thursday...ridge heights will remain suppressed 
/by the broad upper trough along the Canadian border/ through early 
Monday. This will likely be short-lived...however...as the trough 
axis shifts eastward Monday and the upper ridge reamplifies in its 
wake. Expect valley temperatures to peak in the middle-to-upper 90s 
Monday through Thursday. Residual moisture will combine with strong 
heating in this pattern - warranting a slight chance of 
thunderstorms /across southeast Oregon and higher terrain of SW Idaho/each 
afternoon. There remains some hope for cooler temperatures late 
next week as the 12z European model (ecmwf) brings a closed Pacific low inland late 
Friday...but model discrepancies abound and confidence in cooler 
conditions remains low.
