NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
134 PM MDT Wednesday Jul 30 2014 


Short term...the 500 mb level looks to resemble a broad upper high 
pressure ridge with an embedded disturbance moving from the Idaho 
Panhandle into western Montana early this afternoon where isolated 
lightning has been detected. Southern extent of the wave reaches 
into the central mountains around Stanley. This area also has the 
best upper level support for thunderstorms this evening. A red 
flag warning for lighting remains in effect for the central 
mountains until 9 PM MDT. The 700mb wind field is broken into two 
anticyclonic circulation centers...one over Montana and the other 
over eastern Oregon. Axis of contraction looks like it lies along 
the south central and Caribou Highlands. Both of those areas 
should favor at least isolated thunderstorms this evening. 
Thursday...the 700mb circulation over Oregon moves over north 
central Idaho which still leaves some element of orographic lift 
and/or middle level convergence from Monida Pass back towards MacKay 
and Stanley area...and the south Central Highlands. The northerly 
middle level winds may move isolated thunderstorms into the Arco 
desert Thursday afternoon and evening. The GFS model hints at a 
slight contribution of moisture from the remnants of tropical 
disturbance Hernan getting caught in flow over central Idaho. 
Looks like a minimal high level contribution that does not really 
boost precipitable water values much. 


Long term...a disturbance off the Pacific crosses into the Great 
Basin Friday that should boost afternoon thunderstorm activity a 
bit. The extended models are suggesting another surge of monsoon 
moisture around Monday. Otherwise there is a slight chance of 
afternoon thunderstorms each day. Receiver station 


&& 


Aviation...monsoon moisture remains...bringing showers and 
thunderstorms in the afternoons. Brief heavy downpours and gusty 
erratic winds are possible near thunderstorms. Otherwise...light 
winds and VFR conditions are expected through the period. 
Ep 


&& 


Fire weather...monsoon moisture is expected to remain in place 
through the weekend. Isolated to scattered thunderstorms will exist 
each afternoon. Heavy downpours...frequent lightning...and gusty 
erratic winds are possible under and near thunderstorms. 
Ep

Pih watches/warnings/advisories... 
red flag warning until 9 PM MDT this evening idz422-475-476.
