Synopsis
Cool onshore flow will prevail across the region today. A warm
front will approach from the west on Sunday and will lift north
of the region Sunday night. Hot and humid weather will return on
Monday and Monday night as a weak frontal boundary settles south
through the region. Stalled frontal boundary will be the focus
for showers and thunderstorms Tuesday and Tuesday night as it
lifts back to the north. A stronger cold front will approach
from the west on Wednesday and will slowly cross the region
Wednesday night and Thursday. High pressure will build in from
the west for the end of the week.

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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
