Rainfall forecast through Mon night clearly shows much heavier rain to our west. Hydrometeorological Prediction Center (HPC).
Friday 7 Oct 2011 / 5:30 p.m.
A major rain event is taking shape for western Oklahoma and Texas as a deep trough approaches Sunday and lingers into Monday.
Amounts may exceed 5 inches as you get a couple hundred miles west of I-35! The rain potential for Texoma will be highest in the west, and steadily decrease as you move eastward.
The latest HPC rainfall outlook supports this forecast for the best rain coverage and amounts over the western third of Texoma. The heavy rain potential looks to be along and west of a line from Ada to Madill to Gainesville, where an inch to two inches of rain is possible Sunday-Monday.
Amounts will be in the zero to 1/4" range by the time you get to Paris, Hugo and Antlers. Please bear in mind that a slight shift in the trough's path will either boost or decrease rain totals.
