Loving the cloud discussion! Cirrus today. I LOVE Cirrus clouds. Also note a NW flow which mean dry air and warm as the air is going to slope down the mountains towards us (warm airmass aloft)

A vigorous shortwave slides SE through northern New England
today, with a weak surface trough moving through the region
this late this morning.
Morning clouds and spotty sprinkles/sleet pellets will give way to mostly sunny skies (outside of a thin veil of cirrus) and gusty WNW flow this afternoon. Downslope flow should allow temps
to rise into the upper 50s to lower 60s across the coastal
plain, and lower to mid 50s interior (10-15 degrees above
seasonable). HRRR, which does very well in these early season
downslope scenarios was used for temps. This is close to the 90
percentile of NBM.
.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
Ridging aloft will builds in tonight through Wednesday, while
at the surface high pressure slides in from the west tonight and
then gradually east on Wed.
Good radiational cooling conds expected tonight with lows in
the 20s across outlying areas and 30 to around 40s closer to
urban centers. A light flow and sunshine Wed morning should
allow for quick warming, but a strengthening onshore flow as
high pressure slides offshore will result in an increasing
maritime influence, particularly coastal plain. This will likely
result in temps that are slightly cooler than today along the
coastal plain on Wed (lower to mid 50s), with far NW areas
possibly slightly warmer than today (near 60 degrees) with a
greater mixed layer depth.
Upper ridge axis slides east Wed Night into Thu, with a
longwave trough beginning to slide into the north Central US and
Great Lakes. At the surface a series of low pressure systems
will track NE from the Central Plains into the Great Lakes,
while high pressure settles into a Bermuda-type setup and
remains in control locally. This will have a deep SW flow aloft
and waa flow up the East Coast. A weak cold front that passed to
the south of the region today will return as a warm front Wed
Night. Ahead of it, with a strengthening inversion and onshore
flow, stratus development is likely Wed Night into Thu morning. In addition, likely some mid and high cloud cover streaming into the region. Temps Wed night should be mild though with cloud
cover and S/SE flow, generally mid 30s outlying areas to lower
40s city/coast.
Cloud cover and timing of stratus erosion, particularly near the coast will present some challenges for forecast temps on
Thu. With 900 hpa temps around 11-12c, if mixing is fully
realized to this height, temps across parts of NYC/NJ metro and
areas to the N&W have potential to rise into the lower 70s to 75
(near record levels for the date). MOS guidance and model
blends surface temps tend to be too cool this time of year (pre-
greenup) in this type of regime with deep SW flow, good mixing,
and temps aloft running +2 STD. For now, will continue with a
bit more conservative forecast based on forecast time window,
with highs in the 50s along the south coasts (NBM), and mid to
upper 60s for NYC/NJ metro and pts N&W (NBM/NBM 90th blend).
But there is potential for temps to be trended a few degrees
higher, mainly away from marine influence.
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A low pressure system over the Upper Midwest and southern
Canada will allow the pressure gradient to tighten over the area
with high pressure remaining just offshore. This will allow for
a continued S/SW flow over the area with temperatures remaining
above average through the end of the week. The S/SW flow will
bring in more moisture as well allowing for skies to be partly
to mostly cloudy at times. High temperatures on Friday could once again be 10-20 degrees above average and a nice preview of Spring..
Departures yesterday. 20+ above normal from Central Plains north to the border
Power of radiational cooling on display again. Despite upper 60s yesterday, down into the mid 30s here. 30 at the lake. Lows should start heading north soon though. 70+ today
Not as warm as forecast so far today in Fort Worth Texas; still only in the middle to upper 60’s as of one o’clock this afternoon. I feel the clouds are likely holding temperatures down somewhat. It remains to be seen whether tomorrow and Thursday will be forecast busts as well given the increasing humidity and clouds forecast on both days. The next chance for showers and thunderstorms arrive Wednesday night or Thursday.
Annoyed with the high clouds this afternoon. Made it to 70 due to advection. I really need the full sunlight to help warm my apartment. It stays so cold in the morning
At least there was partial sunshine in Atlanta which is sunnier than Fort Worth Texas was today. Temperatures have been hovering around 70 degrees despite weather forecasts calling for partly sunny skies and temperatures in the low to mid 70’s.
Best weather here since early December today. Hit 63F (18C) under a completely sunny sky and lack of a seabreeze. Tomorrow may not hit 60 due to southeast winds off the ocean, but then Thursday and Friday look even warmer with mid 60s forecast during the day and lows in the mid 50s. Some inland areas should hit 70. It's not out of the question here if we get strong downsloping west winds, almost like the Santa Anas in California, but not as dry. These winds are fairly common in spring and early summer, giving us dry heat with large diurnals. Even hit 96 in April - https://thestarryeye.typepad.com/wea...-april.html%20
