Get those galoshes ready -- it's going to be a wet one.

Rain will be soaking Long Island for much of the week, said Peter Wichrowski, meteorologist with the National Weather Service's Upton bureau.

Sunday will see rain start to develop, with temperatures in the upper 40s. The rain will continue Sunday night, coupled with fog, and temperatures will drop into the lower 40s, Wichrowski said.

On Monday, the rain is expected to taper off temporarily, with a chance of sporadic showers during the day, he said. Highs will be near 50.

But come Monday night, widespread areas of rain will redevelop and continue into Tuesday, Wichrowski said. Lows Monday night are expected to dip into the lower to mid-40s.

Highs on Tuesday will be in the lower 50s. The rain is expected to subside by Tuesday night, leaving mostly cloudy skies and low temperatures in the mid-30s, he said.

Wednesday and Thursday are expected to be dry and windy, with highs of 40s during the day and lower 30s at night.

But the dry respite is likely to end with a developing system Thursday night, which is likely to bring increased winds and some showers into Friday, Wichrowski said.
