NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Tucson Arizona 
921 PM MST Thursday Jul 2 2015 


Synopsis...expect a steady increase in the number of storms into 
this weekend. Slower moving storms will start to increase heavy 
rainfall concerns with wet microbursts possible. Daytime 
temperatures will remain close to seasonal normals into this Holiday 
weekend. 


&& 


Discussion...the water vapor imagery this evening indicated an 
elongated upper high extending from northern Nevada into southern 
New Mexico...with its center over northeast Arizona. Storms this 
evening have been confined to the east of Tucson...and appear to 
have fired generally along the moisture discontinuity/boundary 
aloft. Models all show a slight shifting the high axis westward 
overnight...with the 00z GFS and NAM both depicting an area of 
higher Omega at 300 mb to the NE of Tucson...generally east Pinal and 
Graham counties. Believe that this will be the favored area for weak 
convection overnight. 


Storms are still active late this evening across southern Graham and 
eastern Cochise. The latest run of the hrrr indicated that this 
convection will weaken but become more generalized light to moderate 
rain extending into northeast Pima and eastern Pinal into the early 
morning hours. This fits the current trends and larger scale 
picture...so modified inherited probability of precipitation to reflect this scenario. 


&& 


Previous discussion...the atmosphere is temporarily becoming more 
stable with a much weaker flow as the ridge axis reorients from a 
position north of our area to one that is more typically amplified 
east of our area. As this happens the brisk easterly flow is turning 
into an increasing and deepening southerly flow. 


Friday will start to increase a bit as the new flow regime sets 
up...then increasing thunderstorms for the weekend into early next 
week. These will be more typical Summer thunderstorms with heavy 
rain and isolated wet microburst concerns...not the strong 
mesocyclones of Tuesday. 


Saturday will be busy south of Tucson with possible outflows from 
the south impacting metropolitan Tucson in the early evening hours. By 
Sunday and Sunday night the long southerly enhanced fetch will be in 
place with markedly increased thunderstorm coverage. 


At that point the large scale pattern suggests a significant 
weakness undercutting the ridge to our west while high pressure 
weakens to our east. The problem is our mean flow may become more 
southwesterly than southerly with this...pushing the better chance 
of thunderstorms mainly east of our area. There will be a tight 
gradient of storm activity...diminishing from east to west with a 
minor difference in position of larger scale features making a big 
difference in the convection forecast for Southeast Arizona. Best 
guess is that after Monday...western areas will see less coverage 
while southeastern and eastern areas remain busier. 


&& 


Aviation...valid through 04/06z. Thunderstorms in southern Graham and 
eastern Cochise counties will weaken and become more generalized 
light to moderate showers around midnight. The best chance of 
showers will be to the northeast of Tucson in eastern Pinal and 
Graham counties. Slow clearing by daybreak Friday...before another 
chance of thunderstorms Friday afternoon. Brief wind gusts of 30-45 
kts and MVFR conditions possible near the strongest storms tonight 
and Friday afternoon/evening. Otherwise expect normal diurnal wind 
trends. Aviation discussion not updated for taf amendments. 


&& 


Fire weather...adequate moisture and a favorable flow pattern will 
continue to provide an increasing chance of mainly afternoon and 
evening showers and thunderstorms into the upcoming Holiday weekend 
with high temperatures within a few degrees of normal. 


&& 


Twc watches/warnings/advisories...none.
