short term today through Tuesday ...

mid and upper level flow pattern will noticeably amplify during the
short term forecast period as several strong shortwaves dig into the
middle us from the pacific NW and southwestern canada.

After a cold start freeze warning in effect thru 9am for much of
the area... See npwffc for details Monday will be a rather
pleasant day as weak NW flow in the mid levels takes its time
shifting to the sw. A broad area of high pressure will rule the
lower levels. Expect nothing more than some passing cirrus
clouds... Gradually increasing as the day progresses. High temps
upper 50s north to middle 60s central.

Conditions begin to change Monday night as a strong speed MAX slides
down the front range of the rockies. This shortwave... Along with
another digging vort MAX across the upper great lakes... Will help
amplify a broad area of cyclonic mid level flow into the southern us
and gulf of mexico. The lower level response to this will be to push
the sfc high into the western atlantic. This will quickly lead to an
increase in atlantic moisture to the easterly lower level flow
regime. This will result in decent WAA advection and a rapid
increase in low level cloud cover from the south by Tuesday morning.

This also combined with emerging disturbances within mid level
cyclonic flow should allow for some sporadic light precip across the
area on Tuesday. Right now nam12bufr soundings which is preferred
over the GFS given better lower level resolution indicate potential
for drizzle Tuesday morning before becoming more showers through the
day. Overall have kept just slight chance over the area given weak
lift and weak lower level ridge influence.

long term Tuesday night through Sunday ...

the long term period begins with another frontal boundary moving
toward the area from the tennessee valley. This looks to be a dry
front with very limited moisture associated with it. Precipitable
water across the northern tier is only around a half an inch so no
pop inclusion for the far nw. Further south there is a slightly
better moisture profile but definitely nothing to write home
about. Southern stream energy is quite strong as it rotates
through the lower mississippi valley and warrants slight chance to
low end chance pops despite the limited moisture.

Trough scours moisture south of the area for the remainder of
Wednesday with dry northerly cool advective flow. Another light
freeze will be possible across the far northern tier for early
thanksgiving morning. An additional strong shortwave moves through
the tennessee valley and mississippi valley with GFS quicker with
the progression than the ecmwf. Moisture does surge ahead of this
feature as a surface low forms over the gulf. Looks as though it
will only be the SE corner affected by this activity if at all and
will limit chances to 30 percent.


12z update...

vfr conditions expected through today as cirrus gradually increase
from the west. The main concern in terms of ceilings will be
overnight tonight into Tuesday. Low clouds are expected to
rapidly increase from the south and a quick lowering to MVFR and
possibly ifr is expected. Patchy drizzle and light showers may
accompany the low clouds but confidence is not high enough on
coverage to mention in tafs yet. NW winds this morning should
shift to the NE in next hour or so then to the SE this afternoon
and remain there at under 10kts.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
