Climate data for yesterday

Clicking the image at left will give you an idea of the high temperatures reached yesterday. It was in the 90's pretty much everywhere in Vermont, with the hot spots being near the south end of the Connecticut Valley and in the southern Champlain Valley region. Mountain stations were cooler, but the 79 F maximum temperature on Mount Mansfield tied a record set for this date in 1974.

The second image shows the total precipitation that fell yesterday afternoon and evening. The effect of the Green Mountains is strong here. The largest precipitation amounts were in excess of one inch in the area of Mount Mansfield (3.67'' at Underhill, 2.52'' at Jeffersonville) and Jay (1.80'' at Jay Peak, 1.33'' at East Berkshire). In the Northeast Kingdom and Connecticut Valley, less that 1'' fell.

Precipitation is a difficult quantity to get a feeling for. Most areas of the northeastern U.S. get on average about 3 inches of rain in a month. So 3'' is about what you would normally expect to get in month. If that amount falls in a day, you're getting a lot of rain!

Both of these examples illustrate climate data that record weather extremes and totals for a given day. Local climate maps can be retrieved at the NWS-Burlington Office website.
