Timing differences are showing up in the models concerning the arrival time of a strong cold front and associated upper-level storm in the area Monday night into Wednesday. The latest trends are heading towards a slower arrival time of the front, by sometime Tuesday, maybe even early Tuesday evening.
Should the upper-level storm that will be approaching from the west slow down, and dig further south, then the front will be delayed. But if this happens more moisture may get pulled further westward into the local area. Lots of unknowns yet on all of this. At this time only light precipitation is expected.
But make no mistake a big change is coming by Tuesday into Wednesday. Colder temps will be headed our way along with gusty northerly winds, overcast and dreary skies, and possibly some light rain. Depending upon the arrival time of the cold front, high temps on Tuesday could range from the 40's to the 70's.
