Good Saturday and welcome to the last weekend of October. We’ve had a winter preview over the past few days and will hang on to the chilly air for a few more days. Big changes are lurking for Halloween week as our pattern ramps it up a notch.

Our short term weather looks pretty good. After a frigid start in the 20s, afternoon highs will range from 50-55 degrees in most areas. Skies will be partly sunny with some high clouds streaming in. Those clouds are ahead of a cold front that drops in here early Sunday. This is moisture starved, but may spit out a shower.

Temps behind the boundary will be a few degrees colder than what we have today.

Changes begin on Monday as temps moderate toward 60 degrees and some late day clouds increase. A massive storm system will develop across the southern Rockies and that will have a big impact on our weather through the week.

That impact starts Tuesday as we see scattered showers and some thunder working in from the west…

GFS 4

That will have an impact on how warm our temps get. With the rain, it’s in the 50s. Outside of the rain we’re talking low 60s.

That storm will then continue to develop and work toward the Ohio Valley and Great Lakes by late Wednesday into Halloween. With so much going on in the atmosphere… I suspect we will see the models handle this system a little differently as we get closer. For now, here’s the GFS for Halloween…

GFS

Rain, wind and some thunderstorms will roll through here Wednesday and Thursday. Chilly air will filter back in here later Halloween and into Friday.

A bigger shot of cold is likely to dive in here for next weekend…

GFS 2

There’s some possibility of a few flakes flying around that time period. We shall see.

Have a great day and take care.
