A stalled front is finally making it's way north today. That would be the reason for the showers this morning. As it progresses off to the north, we'll dry out this afternoon and see some breaks in the clouds. Temperatures are going to be very mild though.
A strong cold front will approach the region tomorrow. Increasing clouds during the day will turn into showers beginning in the evening. The timing of the precip is going to be very close to coinciding with trick-or-trick festivities. I'm pretty optimistic that the heavier rain won't arrive until later in the night though.
The front moves through Friday morning. Rain and possibly a thunderstorm or two will continue through the first half of the day. We should see precip taper off in the afternoon and by the evening we should be all clear of it, possibly even earlier.
Saturday will be rather pleasant, with cooler temps and plenty of sunshine. A weak disturbance and northwest flow cloud produce some upslope snow showers at night for the favored locations in the northwest portion of the state, but it won't be anything significant.
Colder air arrives Sunday as high pressure will be centered to our west. Even with an abundance of sunshine, temps will be running 12-15 degrees below normal. A frost/freeze is in order Sunday night.
That area of high pressure will gradually move off to the northeast on Monday and Tuesday. Monday looks nice but still on the cool side. Temps will be bumped up a few notches from Sunday. Tuesday looks to see another bump up in temps but increasing clouds thanks to a moist, southeasterly wind flow.
