00z taf cycle
Isolated or scattered convection possible at all three taf sites
until around 04z to 06z Thursday. Otherwise...VFR conditions are
expected through 00z Friday except for some possible MVFR ceilings at
the Amarillo taf site between 04z to 06z Thursday and 14z to 16z
Thursday. Winds will be light...5 to 10 knots or less...and mainly
from the northeast to southeast.
Previous discussion... /issued 252 PM CDT Wednesday Jul 29 2015/
a few thunderstorms may form across the southeast half of the
Texas Panhandle due to the instability from the heat of the day.
But believe the best chance of showers and thunderstorms
overnight will be across the northwest half of the County Warning Area closer to
the upper level dynamics and subtropical moisture plume.
An upper level short wave trough over central New Mexico is
expected to slowly lift north and northeast and then it will
slide eastward across our northern County Warning Area Thursday afternoon into
Thursday night. So a better chance of rain will be found across
these areas during this time frame.
Upper flow becomes more northwesterly Friday and beyond...so daily
chances of mountain convection heading this way is in the cards
through the end of this forecast.
