Mount Washington Valley Forecast

4:19 AM
A weak ridge of high pressure will build over the region this morning as a shortwave trough approaches from the northwest for this afternoon. The cresting high will allow for a bit of clearing early on, but as the trough approaches, clouds will once again return. The trough along with hot and humid air in place over the region, will allow for the formation of numerous convective showers and thunderstorms, especially for the northern half of the state by this afternoon. Overnight, stronger convective activity will taper as daytime instability dissipates; however, upslope showers in the north are expected to continue. Saturday, an area of low pressure will approach from the Great Lakes which will spread in more rain showers across the state and will likely bring a round of thunderstorms by the afternoon as a cold front slowly approaches.
Sunday, the cold front will stall over the region allowing for continued instability around the region. This will continue scattered showers and thunderstorms across the region especially as the state remains on the warm side of the frontal boundary. Monday another low will approach from the Great Lakes region, spreading in a warm front for the region. This will make for a warm and humid day with more rain showers spreading in. The hot and humid conditions along with the front will likely bring another round of thunderstorm activity. Wet and unsettled weather will then continue into Tuesday as the low lifts northeast, dragging a cold front in from the west. With numerous days of rain expected, localized flooding may be a concern across the state by the middle of next week.
