NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
848 am MST Thursday Oct 30 2014 


Synopsis... 
high temperatures will continue to be well above normal through 
Friday...though there will be some high clouds around today. Over 
the weekend...a low pressure system moves into the western states. 
It will bring much cooler temperatures and breezy conditions to our 
region...with highs dropping into the 70s on the lower deserts. Rain 
chances will be slight and confined to the higher terrain. 
Anticipate little change in temperatures Monday... followed by a 
warming trend Tuesday and Wednesday. 


&& 


Discussion... 
satellite this morning shows patches of high cloudiness beginning to 
move into southeast California and SW Arizona just east of a low pressure system 
spinning off the California coast. Trends and model guidance 
indicate the cloudiness will continue pushing across the forecast 
area through this evening. Not expecting this to be opaque enough 
though to cause much effect on surface heating. So expect todays 
high temperature readings to once again to be several degrees above 
normal. In fact...at 8 am readings across the region were at or 
slightly warmer than 24 hours ago. 


Earlier forecast package was pretty much on track. Minor adjustments 
were made to sky...wind...temperature...and dewpoint grids to better 
align with observed conditions and trends. 


&& 


Previous discussion... 
issued 340 am MST Thursday Oct 30 2014 


Today and Friday... 
clear skies across the forecast area early this morning. 
However...that will change very quickly as a batch of high clouds 
moves in from the southwest. High clouds should be just thin enough 
to enable high temperatures today to be as warm as yesterday. The feature 
producing the high clouds is a weak upper low emanating from 
subtropical latitudes. It is being advected northeastward by a much 
larger low pressure system currently centered just west of British 
Columbia. Friday will see less cloudiness as the large system digs 
southward. Thus there will be little change in temperatures Friday 
with readings in the low 90s being common on the lower deserts. Of 
note...the sref continues to generate some modest quantitative precipitation forecast over eastern 
and central Arizona Friday. This is due largely to advecting more 
moisture westward...from a backdoor front...compared to other 
models. Some of the high res NCEP models produce some very spotty 
quantitative precipitation forecast in central Arizona...outside of our forecast area. GFS and European model (ecmwf) 
keep Friday precipitation near New Mexico border. Will keep forecast dry. 


Saturday and Sunday... 
the system tracks inland Friday night through Sunday. A dry cold 
front moves across our forecast area Friday night and Saturday. 
There may be some semblance of a frontal cloud band with it but 
likely this will be shallow. Kept slight chance for higher terrain 
Saturday due to orographic lift aiding the frontal lift. 
Aloft...there looks to be two main short wave/vorticity maxes with the 
trough that will affect Southern California and Arizona this 
weekend. The first one passes just northwest of our area early 
Saturday. The second one brushes US later Saturday into Sunday. The 
second one looks to have the best potential to produce precipitation as qg 
forcing will be better for our area and there will be cooler air 
making precipitation processes more efficient. However...precipitation chances 
will be slight and still confined to higher terrain areas. Main 
impact will be the nice cool down and breezy conditions. Our western 
areas will get most of their cooling all on Saturday. Our eastern 
areas including Phoenix metropolitan will drop about 10 degrees Saturday 
then another notable drop for Sunday leading to highs in the low to 
middle 70s across the lower deserts. 


Monday through Wednesday... 
a couple of trailing vorticity maxes are advertised to carve out a 
prominent short wave trough over the area early Monday into Tuesday. 
The European model (ecmwf) has returned to the idea of developing a closed low within 
the bottom of the trough...centered over Phoenix by 00z 
Tuesday...which is a deeper solution than the GFS. The Gem has a 
similar idea but is faster with the arrival and departure. 
However...the European model (ecmwf) looks to be an outlier with respect to its 
ensemble...the ecens. Also...it is indicative of less run to run 
consistency. The GFS is well supported by the gefs and forecasts 
were weighted more heavily toward that solution. Thus mention of 
precipitation chances ends Sunday night and a warming trend starts Tuesday 
as a ridge begins building in.

Aviation... 
south-central Arizona including kphx...kiwa and ksdl...southeast 
California and southwest Arizona including kipl and kblh... 


Through 20z Thursday...slowly increasing high clouds at or above 25 thousand 
feet. Light wind under 8 knots. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Saturday through Wednesday... 
a seasonably strong cold front will move through the region Saturday 
allowing slightly cooler than normal temperatures to filter into the 
district the first half of next week. Behind this frontal 
passage...wind speeds will increase and become occasionally gusty 
during the afternoon hours...especially Saturday through Monday. 
Gusts to around 30 miles per hour will be possible along ridge tops and through 
favored River Valley locations. Minimum relative humidity values 
will initially only fall into a 25-40 percent range over the 
weekend...but as much drier air moves into the district...humidities 
will fall into the teens Monday and Tuesday possibly leading to a 
somewhat localized elevated fire danger. Otherwise...overnight 
recovery will be good...and conditions becoming more tranquil 
towards the middle of next week.
