Connecticut Snowfall Totals: Nov. 13-14, 2014

Here is a snowfall map that I created using reports from various sources. Many of the reports came from this forum and the National Weather Service. Only social media reports that passed through quality control were considered. All reports gathered were carefully considered and compared before being included. Light rain, with light snow across the higher elevations, developed across Connecticut during the evening hours of November 13th. The steadiest and heaviest snow fell around midnight and t

Connecticut Snowfall Totals: Mar. 7-8, 2013

Here are some maps that I compiled from various sources. Most of the reports came in through the National Weather Service, with a few from this forum and social media reports that passed through quality control. Snowfall amounts were greatest across the higher terrain of Tolland County. This was due to a persistent band of moderate to heavy snow, as well as the altitude as temperatures were marginal through a portion of the event.

Connecticut Snowfall Totals: Jan. 28, 2013

Generally light snow overspread Connecticut from west to east during the morning on January 28th. Snow continued into the early afternoon and at the same time, warmer air moved in aloft. A change to sleet and freezing rain occurred from southwest to northeast, with portions of the I-95 corridor changing over to plain rain. Precipitation tapered off to intermittent drizzle with freezing drizzle across much of the interior by early evening. Snowfall totals were fairly uniform with most areas pic

Closing Out April With A Bang? (severe)

April is seen as a transition month during the severe weather season, as the frequency of tornadoes typically picks up rather quickly through the month. Despite what the calendar has to say, tornado activity has been fairly lackluster so far this month. In fact, after moving well above the average to-date tornado count in late February, the U.S. has steadily been losing ground. As it stands now, through April 18, the U.S. is near average this year for tornadoes, but with a relatively quiet rest

Arkansas Severe Threat: Sunday, March 13

A localized threat of severe thunderstorms, including possible tornadoes, targets Arkansas Sunday afternoon into the evening hours. A compact shortwave trough approaches from Oklahoma during the afternoon, with a modestly warm, moist flow from the south to southeast streaming up the lower Mississippi Valley.   Computer forecast models have been quite consistent with this general threat for quite some time and now that Sunday is approaching, some high resolution, short-term guidance has been re

April Outlook - Central/Eastern U.S.

A colder than average pattern may persist into April across the Great Lakes and Northeast. Based on the information I've been reviewing over the past several days, I have enough confidence to post a temperature outlook for the month of April. As I see it, below average temperatures will likely continue from the Great Lakes into interior New England and up toward Hudson Bay Canada. I expect a continuation of troughiness extending from southeast Canada into portions of the Northeast. While the h

April Forecast Verification for Inland Connecticut

I've been creating daily 6-day forecasts for the better part of this year, with a focus on inland Connecticut. Before making any forecast, I take a close look at the computer model forecasts through Day 6, including a few forecast techniques to see how verification pans out. In April, I had 29 days worth of data, out of a possible 30, to measure forecast accuracy. As expected, forecast error generally increases with time. It is interesting to note a spike at Day 5 and a decrease at Day 6. That

A Look Back at Dec. 29 for Connecticut

Map above is based on reports from various sources, including this board, the National Weather Service and data viewers from across the state sent in. Event Summary: Scattered snow showers reached portions of western Connecticut by late morning on the 29th. This snow was associated with weakening low pressure over Pennsylvania. The main storm began to develop east of Virginia during the afternoon. Steady precipitation overspread the state from southwest to northeast between about 1 and 3 p.m

A Casual Look at the Rest of March

A pattern change is soon underway that will leave much of the U.S., especially the eastern two thirds, feeling spring fever. Unlike patterns in recent years, a prevalent ridge of high pressure off or near the East Coast (“Southeast ridge”) will maintain generally at or above average temperatures for the region. The only exception may be parts of the Northeast, where some backdoor cold fronts could keep temperatures cooler. To the west, troughing across the West Coast should help keep a much-need
