Looking for sunny, seasonable, spring weather? Except for a brief warmup to near 70 on Thursday, there's none in sight for at least a week.

As a large, complex and slow-moving storm system approached the Berkshires, forecasters issued a flood watch for the region, in effect from 6 p.m. Wednesday through noon on Thursday.

On and off showers, some of them intense, are expected to drop one and half to three inches of total rainfall on the county, according to the National Weather Service in Albany, N.Y.

The potential result: Minor flooding on rivers and streams, and likely flooding of low-lying and poor-drainage areas vulnerable to heavy rainstorms.

High winds from the east and southeast, far-below normal temperatures and even a thunderstorm or two are in the mix before a burst of warmth on Thursday offers a brief respite from the raw conditions that have put a damper on outdoor activities.

The heaviest rain was expected by nightfall on Wednesday with winds gusting to 25 to 35 miles per hour at times, except in North Berkshire, where 40-mile-an-hour gusts were anticipated, with very chilly temperatures for the end of April and start of May, forecaster Kevin Lipton stated.

On Thursday, after the leading edge of a warmer air mass pushes through the county, Lipton predicted highs from the mid-60s to low 70s, with possible showers and thunderstorms, all depending on how much sun can break through to destabilize the atmosphere in what he described as a "very tricky" scenario.

The weekend outlook is murky, with plenty of cloudiness, a chance of showers from time to time, and a return to unusually cool temperatures.

At Pittsfield Municipal Airport, April closed out with temperatures near normal, on average, though the first half of the month was unseasonably mild, while the past two weeks have seen mostly chilly days and nights. Average temperatures recorded at Harriman & West Airport in North Adams came in about 3 degrees below normal. The National Weather Service maintains automated observation stations at both airports.
