Near term until 6 pm this evening 6 am... Fairly decent line of showers and embedded thunderstorms moving across NRN me zones this am. Radar accum data giving mixed signals, but bast on yesterday's early morning shra, leaning toward higher amts than radar only estimates, especially where there is thunder occuring. Other than a few spotty showers in the south the S most of the precip in the n this morning, and based on meso models and upstream radar this should be winding down in the few hours. Also, dumping the dense fog advisory. Previously... As I write this some showers are popping up near lk winnipesaukee, right where the hrrr said would several hours ago. I included the slt chc pops in this area just to cover this and will need to monitor for updates. Meanwhile, some weak elevated convection continues to track NE across the NRN zones, and chc pops go thru the first part of this morning there. The coastal plain and foothills are pretty well entrenched in coastal stratus at this point, although fog is limited. The light onshore sfc flow will pick up a little bit this morning and this should make it hard to dislodge the clouds or mix them out, so much of the CWA will stay mostly cloudy thru today. Downslope areas in the NRN zones and the ct vly, will likely see the most Sun today, especially mid morning thru early afternoon, and will likely see more breaks of Sun in interior srn SRN nh this afternoon than many other spots. Considering the onshore flow and the clouds most of WRN me and the interior central and NRN nh. Will like only see highs 70-75, coolest closer to the coast. In the ct valley and interior SRN nh, highs will reach to the 70s with a few spots near 80. After the morning showers, the better chc for showers will be in the N and W zones during the afternoon, with some thunder possible in the ct vly. Short term 6 pm this evening through 6 pm Sunday The best chc for shra tsra will be this evening, as more significant convection develops over ny and vt this afternoon and works east. The trend will be for weakening as it moves into our cwa, however, cannot rule out a small possibility for strong wind gusts in the ct vly late afternoon into evening. This convection will weaken to mainly showers but will track across much of the CWA during the evening before shifting east or dissapating. Otherwise the marine lyr will rule once again tonight with low clouds and fog over much of the cwa. Mins will one again only drop into the low to mid 60s across much of the area. The expectation for now is that Sunday will be better than Saturday, it will be a little warmer with more sun, although it may start with clouds and some fog. The weak that crosses the cwa overnight tonight will shift the light flow more s-sw and this should reduce the influence of the marine lyr with highs ranging from 75-80 across much of the cwa. It'll be a little warmer in interior SRN nh, and a little cooler on the mid coast. There's still a chance for sct shra tsra late in the day, as a very weak 500 mb wave moves over some mid-lvl waa, but thinking that the better chc for precip will be Sunday night. Long term Sunday night through Friday Warm front will approach from the west Sunday night bringing increasing clouds and a chance of showers after midnight. |
Can't rule out a rumble of thunder but not looking for anything too widespread. Low temperatures will dip into the lower to mid 60s. Warm front will lift north and east of the region by Monday with most of the forecast area breaking into the warm sector as a cold front approaches from the west. Looking for oppressive heat and humidity as dew points rise into the lower 70s in southern zones. May see several hours of apparent temps of 95 or better in the manchester nashua section of southern new hampshire. Looking for fairly respectable CAPE to develop across much of the region by early afternoon and showers and thunderstorms will be likely. Shear will increase somewhat in northern zones during the afternoon and evening and may be enough to produce wind damage with stronger storms. Bigger factor will be pwat's of 1.5 to 2.00 inches which will result in heavy rainfall and possible wet micro-bursts in southern and central zones. High temperatures will range from the lower 80s north to the lower 90s south. Expect shower and thunderstorm activity to continue Monday evening as the cold front gradually settles south into the region with this activity diminishing after midnight. Looking for a warm and muggy night with lows ranging through the 60s. Frontal boundary will stall along the maine coast and southern new england by Tuesday morning. This boundary will again be the focus for showers and thunderstorms mainly south of the forecast area but southern new hampshire may get in on the action in the afternoon as heating picks up and a weak shortwave swings in from the west. Highs on Tuesday will range through the 80s to near 90 in the south. Frontal boundary will lift back to the north Tuesday night and will be the focus for continued shower and thunderstorm activity overnight across southern new hampshire and maine. Lows overnight will again range through the 60s. Deep shortwave digging into the upper great lakes on Wednesday will drive a potent cold front toward the region. At the moment timing on the front not ideal but increasing shear later in the afternoon may produce some severe cells in northwest zones by late in the day. Highs on Wednesday will range from the upper 70s north to the upper 80s south. Front will continue to push in from the west Wednesday evening with showers and thunderstorms continuing into Thursday morning. Lows will range from the upper 50s to mid 60s. Cold front may take much of Thursday to push east of the region but expect showers and thunderstorms to finally push east of the area by late afternoon. Cooler and drier air will accompany high pressure building in from the west for late in the week. Aviation 10z Saturday through Wednesday Short term... Coastal terminals and kaug will be stuck in ifr, with a few hours of MVFR possible late morning into the afternoon. Inland at kmht kcon kleb khie will likely see a period ofVFR late this morning thru this afternoon. All terminals should drop back to ifr this evening. Look for an improvement toVFR across the board Sunday afternoon. Long term... GenerallyVFR with areas of MVFR ceilings vsby in showers and thunderstorms. Marine Short term... Some patchy dense fog will be possible today and tonight, otherwise, seas winds stay well blo SCA thru Sunday. Long term... Sca's may be needed on Wednesday. Gyx watches warnings advisories Me...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
