WHAT HAS CHANGED

Lowered this morning's temperatures, especially in the deeper valleys. Lowered temperatures tonight into early Sunday morning, again, mainly in the valleys due to expected excellent radiational cooling conditions. Minor adjustments to valley fog expectations the next several nights. Tuesday is trending cooler behind a dry cold front, with cold temperatures expected Tuesday night.

KEY MESSAGES

1) High pressure over the region will generally keep conditions seasonably mild and dry. A couple of weak cold fronts will move through next week with brief cool periods to follow.

DISCUSSION

KEY MESSAGE 1...

A few high clouds will exit the area early this morning. After a chilly start in the mid-20s to lower 30s it will warm up nicely into the upper 50s to low 60s with plenty of sunshine this afternoon. It will be another cold one tonight with high pressure overhead. Sunday features more sunshine and warm afternoon temperatures in the 60s. Our area remains under high pressure into Monday, with west winds increasing between 5 to 10 mph. This setup will allow for additional warming, with highs likely to reach well into the 60s and even near 70 for the deeper valleys Monday afternoon. Skies will be sunny, except for a few late day clouds moving in from the north.

A weak, moisture starved cold front will drop south through our area Monday night into Tuesday; providing a glancing blow of cooler air. Surface winds shift out of the north. Monday night features lows in the upper 20s to 30s. Tuesday will see more sunny and dry conditions, but much cooler highs only in the upper 40s to 50s areawide. Canadian high pressure settles overhead Tuesday night, bringing light winds, clear skies and cold lows well down into the 20s and low 30s.

Dry and mostly sunny weather continues for Wednesday, with a slow moderating trend. South winds increase on Thursday out ahead of another weak frontal boundary. Expected a few clouds around, but warmer temperatures well into the 60s are in the forecast. Overall, other than a few slight chances for brief light rain, it now looks to remain dry and mild right through Halloween.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/

Mainly VFR conditions are expected through the next 24 hours (at least through 12Z Sunday). The one exception is expected to be at KELM early this morning and then once again late tonight/early Sunday morning with valley fog likely resulting in IFR to VLIFR visby restrictions.
