    Northwest Cold Late Next Week

    2/03/2014, 12:35:49 AM

    Models have been trending toward a colder and colder weather pattern in the Northwest by Thursday and Friday next week. A cold upper-level trough will develop at the same time cold, arctic air will move west in the low levels coming out of western Canada. The change between now and next Thursday is pretty significant if our current models are right.

    Here are surface temperatures, one map from this afternoon and the second map from Thursday afternoon Feb. 6.

    Friday Afternoon:

    Thursday Feb. 6:

    This shows the impressive temperature drop even west of the Cascades and the cold will drop south too after Thursday. California could share in this cold weather with frost and freezing temperatures becoming widespread.

    This is something to watch to see how all this plays out.
