WHAT HAS CHANGED

No significant changes were made to the forecast. Increased winds this afternoon, and lowered temperatures overnight tonight into Wednesday morning to account for radiational cooling under strong high pressure.

KEY MESSAGES

1) Breezy and chilly weather will continue today, with scattered rain and snow showers through this afternoon. Snow showers are expected to result in minor accumulations.

2) High pressure and drier weather is expected for mid-to-late week. Near to below normal temperatures expected Wednesday, and will give way to moderating conditions for the second half of the week.

DISCUSSION

KEY MESSAGE 1...

A weak system is currently bringing light snow showers across the Southern Tier and portions of Central NY. This will continue through late morning/early afternoon, which will result in minor accumulations up to an inch of snow for most places, with possibly up to 2 inches in higher elevations west of I-81 in Central NY. As showers taper off going into the early afternoon, high temperatures are only expected to reach the low to high 30s, and the low 40s for the Wyoming Valley, as colder air pushes in from a high pressure system from the northwest. These temperatures are much below average for this time of year, which is usually in the low to mid 50s for early April.

KEY MESSAGE 2...

Another stretch of dry weather expected after today's showers as high pressure builds in from the northwest, allowing for area rivers, streams, and lakes to start to lower a bit. Overnight tonight into Wednesday morning is expected to be quite cold, as strong, dry high pressure will likely allow for radiational cooling to occur. This will likely result in low temperatures in the teens.

With zonal flow and even a little ridging aloft setting up weak warm advection, temperatures will be on the rise Wednesday through Friday. High temperatures are expected to go from the mid 40s and lower 50s Wednesday to the 60s area-wide by Friday. While Wednesday night still looks chilly, overnight lows return to the 40s Thursday and Friday nights. A frontal boundary looks to approach the area later Friday or Saturday, but with high pressure expected to be over the Southeastern U.S. blocking moisture-rich air coming up from the south, this system looks to become pretty moisture-starved by the time it reaches our area.

AVIATION /06Z TUESDAY THROUGH SATURDAY/

Scattered snow showers are moving across the Twin Tiers. These showers have produced brief periods of IFR visby and ceilings. Another line of snow has developed over western NY and if it holds together, will bring another round of potential IFR snow showers starting around 09z or so, lasting until 10-11z. Tempos for IFR visby have been introduced at all terminals to account for these showers. Prevailing MVFR ceilings are expected through the overnight hours. BGM/ELM should lift to VFR in the morning, while ITH/SYR/RME will see longer MVFR ceilings thanks to lake effect clouds into the afternoon. All terminals will be VFR by the late afternoon.

AVP is expected to remain VFR through the TAF period.

Winds will pick up again in the morning, out of the NW with gusts of 20-25kts expected into the late afternoon hours.

Outlook:

Tuesday Night through Thursday Night...Mainly VFR.

Friday through Friday night...A weak frontal zone may encroach into the area with a chance of rain showers and associated restrictions.

Saturday...Mainly VFR.
