Report by Paula Antolini, January 23, 2019, 8:02AM EDT

A cold front approaches the region today and tonight and passes through during Thursday. This will bring a chance of rain this afternoon for some areas, however rain will become likely across the entire region tonight and continue into Thursday. The rain could be heavy at times during Thursday, and should end by late afternoon. Temperatures will rise through the day today, and continue to rise tonight and Thursday morning. High temperatures for Thursday will be well above normal due to southerly winds.

The National Weather Service in Upton has issued a FLASH FLOOD WATCH IN EFFECT FROM THURSDAY MORNING THROUGH THURSDAY AFTERNOON.

Flash flooding of urban and poor drainage areas, as well as small streams will therefore be possible Thursday.
