Winds are pretty tough to gage or predict. I like to use
-THIS- website to predict stuff over the next 3 days or so.
It's more of an aviation tool, but it works as a descent rule of thumb for hiking. For instance, You can see that winds aloft (3000') right now at 1600 hrs UTC (remember UTC = ETS+4) over the adirondacks are around 40-55 knots (45-60 MPH). They may not be quite that high, but, you can surly bet it's blowing quite nicely right now. Toggle the time to 1800 UTC, 30 Sep 2005 (which is tomorrow at 2:00 PM) and you'll see the winds are down to zip.
You can goof around with temps too and you'll find that lows at the 3000' range will dip to about 0 C (32 F) tonight. Looking at our example of 1800 UTC, 30 Sep 2005 (2:00 PM ETS) you'll see that along with light winds you can expect temps of between 5-10 c (40-50 F).
Cool huh, I've found it very helpful (as a rule of thumb), particularly in winter. you can check things out at 6000' too for those higher summits
