WHAT HAS CHANGED

Adjusted temperatures slightly lower tonight to account for clearing skies and light winds. Otherwise, only minor adjustments were made to overnight lows as developing southwesterly flow may hinder radiational cooling.

KEY MESSAGES

1) Cool and mostly sunny today with another chilly night expected mainly east of I-81 with frost potential.

2) Fairly quiet rest of the week with a weak trough mid-week followed by more high pressure for the weekend.

DISCUSSION

KEY MESSAGE 1...

A frost advisory remains in effect early this morning for Bradford, Susquehanna, and Wyoming counties, where winds are lighter and skies have mostly cleared. Elsewhere, cloud cover remains across central NY with northwest flow off Lake America and lingering wind guests helping to mitigate frost formation. High pressure moves overhead today, bringing mostly sunny skies and northwest flow. Temperatures remain cool, with highs only reaching the low to upper 50s. Winds will be lighter than yesterday, generally under 10 knots with gusts up to 15 knots.

A ridge axis begins to nudge into the region this evening and overnight, allowing winds to shift southwesterly. Despite clear skies and lighter winds warm air advection should keep temperatures from falling near freezing. Cold air will remain entrenched for one more night across areas mainly east of I-81, where widespread mid to upper 30s are expected. Farther west and into the Wyoming Valley, continued warm air advection should keep temperatures in the low 40s.

KEY MESSAGE 2...

Southwesterly flow continues to advect warmer air into the region Wednesday and Thursday, with highs in the mid to upper 60s and lows generally in the 40s. Otherwise, fairly quiet and mostly dry weather is expected through most of the week. A weak shortwave trough looks to move through Wednesday night into Thursday, bringing a chance for rain showers, mainly across north central NY. A cold front associated with the aforementioned through will bring cooler temperatures Friday and Saturday, with highs in the upper 50s to mid 60s, though conditions should remain dry. High pressure then builds back into the region for the weekend, with temperatures rebounding into the mid 60s to low 70s by Sunday.
