PREV DISCUSSION... /Issued 251 PM CST Mon Nov 28 2016/
One upper trough will push across the Panhandles tonight and another
will move across the forecast area by late Tuesday and Tuesday night.
A cold front will move through the Panhandles late tonight and early
Tuesday with dry conditions continuing through at least the middle of
the week. Long wave upper trough will track east across the Rockies
by late Friday into Saturday and cold front pushes into the forecast
area Thursday and then exiting the Panhandles by Thursday evening.
Low level moisture will advect north and west the long way up the Rio
Grande Friday...spreading into the Panhandles by Friday night.
Initially...rain showers will move north into the Texas Panhandle
Friday but then strong cold air advection by Friday night will allow
the precipitation to change over to snow across most of the forecast
area Friday. A mix of rain and snow possible mainly over the
southeast Texas Panhandle Friday night where near freezing min temps
expected. Due to the progressive nature of the upper
trough...precipitation should quickly end from west to east across
the Panhandles by late Saturday. Snow may linger into Saturday
morning before changing over to rain or rain and snow mix Saturday
afternoon or ending completely. Drier and moderating temps Sunday
through early next week.
