NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
935 am CDT Friday Oct 31 2014 


Update... 
no updates necessary to the short term forecast. Looking at 9am 
observations and visible satellite...clear skies and temperatures in the 
low to middle 50s across North Texas. Winds were out of the north 
around 5 to 10 kts in most areas. Sunny skies will prevail today 
and temperatures are expected to warm into the 60s to near 70 in 
some areas this afternoon. Winds will remain out of the north and 
be on the increase with gusts to 20 kts by this afternoon. By 8pm 
this evening winds and temperatures will decrease and conditions 
will be similar to what they were at 9am with clear skies and 
temperatures in the low to middle 50s across most of North Texas. 
Still looking at a very good chance for some beneficial rains 
early next week. Right now model consensus is showing Tuesday as 
the most likely day for widespread rain of at least 1 inch area 
wide. The challenging part in the forecast continues to be what 
happens beyond Tuesday. 


Hoeth 


&& 


Aviation... 
/issued 644 am CDT Friday Oct 31 2014/ 
VFR conditions to continue at all sites today and tonight. North 
winds will increase to 15-18 kts this morning as surface high 
pressure builds into Texas. A few gusts up to 25 kts possible from 
late this morning into this afternoon. Wind speeds will diminish 
to under 10 kts after sunset. Other than a few afternoon 
stratocumulus clouds...skies are forecast to remain clear through 
tonight.

Previous discussion... /issued 454 am CDT Friday Oct 31 2014/ 


Short term... 
precipitation and accompanying cloud cover is exiting to the 
south. The associated cold front appears poorly defined in the 
nocturnal wind field...but north winds are in place across nearly 
all of north and central Texas. Where winds are calm or near 
calm...the dew point spread should preclude any ground fog...even 
where Thursday rain was sufficient to wet the ground. Gusty winds 
at the surface are as far away as Kansas...but the wind profile 
from The Fort Worth 88d radar is currently indicating 40-knots winds 
at 2kft above ground level. Expect the winds will increase considerably after 
daybreak...with gusts of 25 to 30 miles per hour. Even with abundant 
sunshine...high temperatures will only reach the 60s across much 
of North Texas today. 


The winds will diminish after sunset...but light northerly flow 
will allow dew points to fall another 10 degrees before daybreak 
Saturday morning. However...the winds will be light enough that... 
when coupled with clear skies and very dry air...temperatures will 
plunge into the 30s. Temperatures are expected to reach freezing 
in outlying and low-lying areas of northern zones. As this will be 
the first freeze of the season...a freeze warning will be in 
effect for areas along and north of a line from Graham to Sulphur 
Springs. The winds will likely be strong enough to prevent ground 
temperatures from reaching the dew (frost) point...even where 
2-meter temperatures are at or below freezing. As a result...frost is 
also unlikely in areas that see lows in the middle to upper 30s... 
even though dew points will be below freezing in those areas as 
well. Even so...at these temperatures...any slight variation in 
wind or moisture profiles could result in a killing frost...even 
in areas where low temperatures are above freezing. As such... 
care should be taken with any sensitive vegetation. 


25 


Long term... 
a trough continues to deepen as it approaches the West Coast. It 
will swing east through the western states...passing the Continental 
Divide on Monday. At that point...southerly flow within several 
thousand feet of the surface will surge rich Gulf moisture into 
North Texas...beneath destabilizing southwest flow aloft. Precipitable water values 
will soar above 1.5 inches. Training echoes of considerable 
precipitation efficiency may precede a frontal passage on Tuesday... 
after which elevated heavy rain may persist. A cut-off low is now 
the consensus among the extended models though there is some 
disparity in its placement. But even with this disparity...there is 
remarkably good agreement for a cut-off on day 5-6...hence we have 
some of the highest probability of precipitation you will ever see that far out in the 
forecast...including 70-80 on Tuesday. Probability of precipitation have been reduced for 
Thursday...but depending on the eventual anchoring Point of the 
cut-off...the end of the rain event may be later in the week.
