DISCUSSION

1034mb surface ridge sits just to the northeast of the area. Dewpoints are in the upper 30s to low 40s with clear skies and calm winds. We appear on track for a very strong radiational cooling event through the next few hours which should lead to the first widespread frost of the season.

Another strong upper ridge builds in over the central Plains through the next few days and keeps our pattern blocked up through the end of the week. We still look on track for dry and pleasant conditions with seasonable highs in the 70s and lows in the 40s. Guidance consensus is strong in keeping that pattern in place at least into next weekend.
