We have a last batch of showers crossing the area at this hour ahead of a cold front. There are some thunderstorms in this batch, mainly affecting NW NH at this hour. Isolated to scattered showers overnight.

Impacts:
*Convective showers associated with a cold front may aggravate ongoing snowmelt flooding in the White Mountains early this evening, but are not expected to significantly add to totals.

Widespread rain has moved out of our forecast area, but scattered showers continue in it is wake as the area remains under broad cyclonic flow. Therefore, the Flood Watch has been cancelled, but runoff and snowmelt continue and so small stream and river rises will as well. For this reason, areal Flood Warnings and Advisories remain in effect across the north. Confidence is increasing in some convective showers/thunderstorms moving up the Connecticut River Valley around 5-6 PM ahead of a cold front. I wouldn`t expect anything rising to the level of severe, but these showers could contain some graupel or small hail as well as brief heavy rain. Should these storms pass over the White Mountains they may aggravate the flooding situation there, but would not add any significant totals. Elsewhere instability is limited by the onshore flow, so any storms should be confined to western New Hampshire.

Patchy fog remains in the forecast through tonight as dewpoints remain elevated and subsidence behind the cold front may lock in some boundary layer moisture, however the front may also scour out a lot of that low level moisture, and give us a clearer night. Either way, low temperatures look to bottom out in the 40s area wide.

Chances for rain showers will continue Saturday as the area remains under broad cyclonic flow and a secondary cold front sweeps through. Skies will remain mostly cloudy with highs in the low to mid 50s across much of the area. The aforementioned front will work to clear things out south of the mountains, but upslope snow showers look to continue across the higher terrain through the overnight hours with light accumulations possible. A period of breezy winds, 20-25 mph, is also likely in the wake of the front and as low pressure makes its final departure to the north. Low temperatures Saturday night look to be pretty uniform as cold air advection cools northern zones into the lower 30s and mostly clear skies help areas to the south cool into the low 40s.

Long range:
Current double omega block across North Americas mid latitudes and surrounding oceans, does start to weaken and flatten a bit a bit later this weekend, but troughing stays nearby through the week, although, we will be under W-NW zonal flow early next week which should allow for 2 or 3 mostly dry days in the period. For the most part temps run near to a little above normal through the period. Late next week the chance for a steadier rain returns as troughing shifts in from the west.

Sunday will feature a bit of a break with partly sunny skies as a weak ridge moves across the area in the morning. Clouds are likely to increase in the afternoon, with some showers possible late in the day, especially across NH. It will be mild with highs around 50 in the mountains to 55-60 in the south. The best chance for showers across the region will be Sunday evening, as a weak, and fast moving wave moves through. Showers will be light, and most of the forecast area should see at least some clearing by daybreak. Lows range from the mid 30s to the 40s, north to south.

As we transition to more zonal flow on Monday, warmer air will move in but we still will see some clouds as we shift away from cyclonic flow aloft. So, partly sunny covers it, but it will be a bit warmer with highs mid 50s in the mountains to low 60s in the south. It'll be a little breezy as well with westerly wind gusts to 20-25 mph. As the surface high builds to the west Monday night, it will clear out, but there should be enough flow to prevent widespread radiational cooling, but the sheltered mountains valleys will likely decouple, and mins will range from the low 30s in the mountains to the upper 30s in the south. Tuesday looks mostly sunny and even warmer, as surface high crosses into the region with highs in the mid 50s in the north to mid to upper 60s in the south. WE could still eek out a decent Wed, with clouds moving in during the afternoon, although will see more onshore flow developing, especially near the coast, so while highs may climb into the low to mid 60s in the southern half of NH, they will be limited to the 50s on the coast and in in the mountains.

As the ridge moves out Wednesday night into Thursday, am upper level trough will stretch across the NE from west to east, and this brings the potential for mainly rain across the region, potential in several rounds Thursday into Friday.

Manchester, NH:  Last update:  4/12 - 8:03 AM

The latest system (sharp front) coming through today with a round of rain and gusty winds in places. The weather settles down a bit into next weekend, and then we are looking at a warming trend into early next week.

The wind will pick up today out of the south as a strong front approaches. That will allow temperatures to surge back into the 60s in places this afternoon. Periods of rain and downpours are likely in the morning, with over 1" of rain possible in spots. A flood watch is posted for the North Country as the rain in combination with snowmelt will allow for a response by the rivers and streams. A wind advisory is in effect for the coast through 4pm as SE gusts could be over 40 mph.

Lingering clouds along with some patchy drizzle and fog later tonight. Lows will be in the 40s by morning.

Lingering clouds (passing showers, especially up north Saturday), and partly sunny skies on Sunday. Warm with temperatures into the 60s on Monday.
