36 years is a long time to be at one place & doing just one thing. It has been great fun to forecast our challenging weather. But I'm very fortunate that our weather has been calm & quiet as it would be rather difficult to focus on a difficult forecast.

The Mt. Morris Dam has been, and continues to be, one of the greatest investments for our community... Why? Flood mitigation! After yesterday's heavy rain the water level behind the dam has risen 36 feet in about 24 hours. Rochester again is saved by the dam...

The track of the storm, so far, has been surprisingly consistent on most of the computer models. This fact continues to give us confidence that this storm will have a big impact on WNY. Join us at halftime during the game on News 10 NBC for a complete look at the timing.

First Alert Weather Team tracking rain. Do not anticipate severe storms - so damaging wind or tornadoes are not a real risk- but heavier rainfall MAY produce localized flooding. Greatest potential will be late this afternoon into the overnight. Yellow Alert Day continues...

We got the rain starting and we can't seem to turn it off... Amazing rainfall totals with 1.5 to 3.7 inch measurements common across WNY during the last 24 hours. The ROC Airport set a record for the day & this was a record that has stood since 1873 (148 years of record keeping).

Great for snow lovers! This map shows the extent of snow depth across the U.S. with 73.2% of the lower 48 covered in snow. By some estimates, this is the greatest daily amount of snow since 2003 (since this data was first measured).

It COULD be argued that the high wind is the worst part of this storm.... But there is also poor visibility, sub zero wind chill and Lake Erie squalls. Here Highest wind speeds thus far for Western New York. NYS Thruway is now closed from exit 46 to the PA border.

It is truly amazing when it is the 7th warmest August in recorded history for ROC, yet we never reached 90° for any single day. So how did this happen? It was the huge amounts of humidity which kept the overnight low temps so warm.

Usually the start of spring (vernal equinox) begins on March 20th or 21st, but not this year. This is the earliest spring equinox in 124 year (since 1896). Remember, this is the point when sun crosses the equator on it's annual trek into the northern hemisphere.
