High pressure will fill into the area tonight bringing light winds to much of the area. East of the James River and especially across parts of northwest Iowa winds will remain light all night andn these locations will see the highest threat for a killing freeze and widespread frost.
Cool tonight with winds turning sw to westerly allowing for warmer air to begin its return.
417 AM CDT WED OCT 12 2016 Latest observational data is showing that the incoming cold front has now entered the Oklahoma Panhandle.
147 AM EDT Wed Oct 12 2016 High pressure will allow for dry conditions across the region through most of the daytime hours on Wednesday. A cold front will move through Wednesday night bringing showers and cooler weather to the region. Clouds will increase through the day in advance of a cold front that will move through Wednesday night. Due to this increased precipitation chances with the highest chances across northern portions of the region. With the passage of the cold front cooler air will work into the area.
414 AM EDT Wed Oct 12 2016 A ridge of high pressure will bring one more day of dry weather to eastern Kentucky today. The good weather will come to an end overnight, as a cold front approaches from the northern and central plains.
255 AM EDT Wed Oct 12 2016 Rain-free, mild weather will continue through tonight, as high pressure slowly retreats off the coast.
431 AM EDT Wed Oct 12 2016 Rain-free, mild weather will continue through tonight, as high pressure slowly retreats off the coast.
1211 AM CDT Wed Oct 12 2016 An upper trough will slide east across the northern plains tonight. The sfc cold front was passing through our far southeastern counties around Beloit as of 3 pm and cold air advection will continue throughout the night across the entire forecast area.

1116 PM MDT Tue Oct 11 2016 Primary near/short term meteorological concern is impact that an approaching sharp cold front will have over portions of the forecast district from later tonight into Wednesday. PV analysis and forecast model soundings suggest that a sharp cold front will be moving across eastern portions of the forecast district later tonight causing forecast maximum temperatures on Wednesday to run some 25F to 30F colder(over eastern sections) than maximum temperatures noted this afternoon in combination with areas of low clouds and possible drizzle over some eastern locations.
300 AM EDT WED OCT 12 2016 Dry and cool high pressure will ridge southward and into the forecast area through Wednesday.
450 AM EDT Wed Oct 12 2016 Cool and dry high pressure will extend over the area from the north through tonight.
A broad, fairly flat upper level trough will move into our region overnight into Wednesday. A large area of high pressure at the surface will continue to stretch from the Gulf Coast northeastward through most of the eastern CONUS. Along with the high pressure, very dry air will persist at mid-levels, with RH values of 5-10% at 700 mb expected overnight through the rest of today. Temperatures will continue to drop into the 50s across inland areas with low-mid 60s near the Gulf Coast during the early morning, rising back to the low-mid 80s in the afternoon under mostly clear skies and light northeasterly winds.
350 AM CDT Wed Oct 12 2016 The well advertised cold front has crossed into the CWA as of early Wednesday morning and will continue to work its way southeast through sunrise. This has brought 60 degree temperatures down to the lower to mid 50s behind the frontal boundary. Afternoon temperatures will linger in the lower 50s across most areas, with values approaching the mid 50s well south of the Missouri River. Though steep mid-level lapse rates are noted, marginal elevated instability overhead a capped environment will reduce the potential for strong storms ahead of the cold front. Could see temperatures at or below freezing for northwest Missouri tonight, and temperatures along and south of the Missouri River dipping into the mid 30s with radiational cooling underneath clearing skies.
Scattered showers and thunderstorms will remain possible overnight across parts of Northeast Oklahoma into far Northwest Arkansas as a cold front approaches. east of the dryline and south of the approaching cold front in a ribbon of higher dewpoint air. with some increase in coverage overnight as the cold front nears.
Winds will veer to W-NW between 12Z-15z most areas ahead a cold front, but pre frontal winds will still mostly be less than 10kts.
Where those winds kick in, it should stay above freezing with lows hovering in the mid 30s.
The strong cold front currently into south central KS will be near the I-44 corridor around noon and through the western AR and SE OK by mid evening.
125 AM EDT Wed Oct 12 2016 High pressure east of New England will allow an onshore flow to develop, with low clouds spreading into the area tonight. Relatively cloudy conditions will last through Wednesday night ahead of an approaching cold front.
A ridge of high pressure will bring one more day of dry weather to eastern Kentucky today. The good weather will come to an end overnight, as a cold front approaches from the northern and central plains.

weakening qg ascent as upper trough expected to the trof axis shifting to the east. High pressure at the surface and aloft will be over the region. Overall much cooler with a dry and stable airmass in place this afternoon and tonight. and a lee side trough starts to form over eastern CO.
A relatively dry atmosphere with high pressure overhead will provide VFR conditions and a light northeast to east wind much of the this evening. Latest TAF package continues to indicate the lower conditions in a TEMPO group. Dewpoints, even in the Lower Valley, have again mixed out to the low-mid 60's F. Dry air and high pressure aloft are yielding mostly sunny skies. Coastal trough offshore seems to be underperforming, per satellite and radar imagery, so have trimmed back PoP's there for the remainder of the afternoon and this evening. Meanwhile, at the surface, SE winds become re-established on Wednesday as surface ridging retreats toward the NE and pressure falls over the Panhandle region.
Currently a cold front extends from northern Wisconsin through northwest Missouri and into the Oklahoma panhandle. Temperatures will be quite warm again today with highs in the low to mid 80s. The cold front will move through the forecast area tonight with scattered thunderstorms expected ahead of the front.
400 AM EDT Wed Oct 12 2016 High pressure will remain centered off the northeastern United States coast today.
352 AM CDT WED OCT 12 2016 A cold front remains just to the northwest of the central IL forecast area early this morning. The main upper level trough will progress into the area mid morning through evening as the cold front progresses from Galesburg through lawrenceville bringing an active period of showers and thunderstorms. highs ranging from 64 in Galesburg to 77 in Lawrenceville can be expected as cooler air starts moving in by mid morning in Galesburg.

505 PM MDT Tue Oct 11 2016 18Z Water Vapor imagery and RUC analysis indicated large H5 trough over the northern Rockies with fairly zonal flow across western Kansas and eastern Colorado. initial surge of cold air behind cold front has pushed across much of the area. followed by timing and impact of strong cold front tonight. Pocket of low static stability in place tonight as strong cold front sweeps across the area around 6z.
Solutions in decent agreement timing a cold front through KCDS and KPVW near 14z and KLBB near or a little prior to 16z. Low level flow should gradually veer more westerly by daybreak Wednesday in advance of a fast moving cold front. Cold front still expected to arrive mid to late morning across the area with gusty north to northeast breezes. /issued 253 PM CDT TUE OCT 11 2016/ The main story in the forecast will be the cold front for tomorrow. The cold front will bring an abrupt end to well above seasonal average temperatures.
Clear, drier, and colder tonight behind last night's cold front, but already by Wednesday morning warmer westerly flow will come in aloft.
Otherwise, the cold front appears to be progressing a little faster than expected, with KDMX radar showing the frontal boundary arcing across central IA. Afternoon temps in the low to mid 70s are approximately 5- 10 F degrees above normal. Mild ahead of a sharp cold front which is currently bisecting Minnesota and eastern South Dakota. This is going to be an anafront or a cold front with precipitation focused behind the sfc wind shift. High pressure and a dry, cool air mass build in (PWATs down to 0.
Another day of dry and warm weather is in the books as mid-level zonal flow and surface ridging have prevailed across the area. Warm and dry conditions will continue through the forecast package as zonal flow aloft and high pressure near the surface continue to dictate our forecast.
A cold front will move south into West Central Texas tomorrow reaching KABI around 20Z tomorrow afternoon.
A deep layer dry airmass remains in place across the region this evening as upper level high pressure continues to ridge across the Gulf of Mexico and into the southeastern states. Light flow generally from the east will continue to usher in dry air in the lower levels, though models indicate some moisture working in aloft, resulting in some scattered high clouds through the period. Afternoon highs on Wednesday will range from the low 80's across south central Alabama to mid 80's across southwestern Alabama and southeastern Mississippi.
1042 PM CDT Tue Oct 11 2016 Surface ridging holding over the eastern areas which has shunted the deeper moisture west. Cold front over KS this evening should push south and most of the guidance showing the front slowing and stalling between Dallas and Waco Wed night/Thu morning. Fairly strong ridging (591-592DM) over S TX should preclude that big of southward push. Otherwise, ridging over the NW Gulf will remain in place for much of the period, with a few upper lows moving across the Great Plains to the north.
638 PM CDT Tue Oct 11 2016 An upper trough will slide east across the northern plains tonight. The sfc cold front was passing through our far southeastern counties around Beloit as of 3 pm and cold air advection will continue throughout the night across the entire forecast area.

1038 PM EDT Tue Oct 11 2016 High pressure will allow for dry conditions across the region through most of the daytime hours on Wednesday. A cold front will move through Wednesday night bringing showers and cooler weather to the region. Clouds will increase through the day in advance of a cold front that will move through Wednesday night. Due to this increased precipitation chances with the highest chances across northern portions of the region. With the passage of the cold front cooler air will work into the area.
/issued 302 PM CDT TUE OCT 11 2016/ Latest surface analysis showed a 1032mb high over northeast United States with ridge axis extending southwest to Georgia to Louisiana. An inverted trough was located over west Gulf of Mexico. Upper air analysis showed the over northern Mexico with ridge axis east across north gulf to north Florida. 18 Surface inverted trough over west Gulf will continue to push west.
/Issued 303 PM EDT Tue Oct 11 2016/ The quiet fall like weather pattern will continue as high pressure remains anchored over the eastern third of the country. The high pressure influence will continue to produce a dry forecast with mostly clear skies and a persistent cool easterly wind flow. resulting in cooler than normal lows mostly in the 40s once again tonight. resulting in slightly warmer lows in the upper 40s to mid 50s across the area. as mid-level cyclonic flow persists across the Midwest and Great Lakes and a ridge centers over southern TX/eastern Mexico. This places the CWA in a zonal flow in mid/upper levels while the relentless sfc ridging down the Appalachians into Ga finally begins to break up as next weak frontal system approaches.

High pressure has moved off to the east with return southerly flow bringing slightly warmer temperatures to Middle Tennessee this afternoon.
646 PM CDT TUE OCT 11 2016 An area of low pressure over northwest Ontario and Minnesota, and its cold front, will continue moving east through the region through tonight, with the front not exiting the eastern forecast area until the wee hours of the morning. While some light drizzle is possible near and behind the front this afternoon, light rain will become more likely by this evening when the upper level trough approaching from the west begins to result in more substantial height falls and produce more synoptic lift across the region. The upper trough moving through the region will give enough synoptic lift to help produce widespread broken/overcast cumulus. Temperatures will struggle to reach the lower and middle 40s.
Clear skies will continue tonight across the forecast area as the upper ridge axis remains across the region. By Wednesday afternoon, the models indicate that a weakening frontal boundary will shift southeast into the Lower Ohio valley region with scattered showers/few storms possible.
The clouds will hold temperatures warmer the areas that have clouds.
Southerly winds overnight look to stream MVFR conditions into parts of Eastern Oklahoma and Northwest Arkansas ahead of a cold front approaching the region. /Issued 258 PM CDT TUE OCT 11 2016/ A cold front is poised to move through eastern Oklahoma and western Arkansas on Wednesday with noticeably cooler temperatures expected across northeast Oklahoma on Wednesday afternoon.
914 PM EDT Tue Oct 11 2016 High pressure will slide off the New England coast overnight.
Based on the orientation of the low-level wind field and moisture gradient, AFW and FTW may remain on the western fringes of the MVFR cigs. For the DFW extended TAF: an abrupt north wind shift will occur as a dry cold front pushes into the region. Meanwhile, a northern stream mid-upper trough was evident in water vapor loop nearing the northern Rockies early this afternoon. This trough will move east in a fairly progressive flow pattern across the northern plains tonight through tomorrow sending a cold front south toward our area. This cold front should reach the northwestern edge of the forecast area by mid afternoon tomorrow and then progress through much of the area during the evening. The cold front should slow and become diffuse Wednesday night.
718 PM EDT Tue Oct 11 2016 High pressure will maintain dry weather through Wednesday.
1100 PM MDT Tue Oct 11 2016 18Z Water Vapor imagery and RUC analysis indicated large H5 trough over the northern Rockies with fairly zonal flow across western Kansas and eastern Colorado. initial surge of cold air behind cold front has pushed across much of the area. followed by timing and impact of strong cold front tonight. Pocket of low static stability in place tonight as strong cold front sweeps across the area around 6z.
1002 PM EDT Tue Oct 11 2016 Cool and dry high pressure will extend over the area from the north through Wednesday as a weak trough of low pressure lingers offshore.
The upper pattern is defined by a broad ridge of high pressure over Northern Mexico and Southern Texas, and a low amplitude trough moving into California from the Pacific. Upper trough will drag some high clouds ahead of it into Arizona Wednesday afternoon and evening, otherwise no significant weather. A ridge axis will extend from the Texas gulf coast westward into the eastern Pacific ocean west of the Baja peninsula, with an active northern branch of the jet stream and a series of systems moving through the northern tier of states through the forecast period.
1036 PM EDT TUE OCT 11 2016 Currently - A large area of high pressure extending from the New England States, down the Atlantic Coast and continuing along the gulf coast is responsible for moderate to fresh northeast breezes. Short Term Update - Moderate to fresh northeast breezes will prevail overnight due to the high pressure system to our north. A large high pressure system stretching along the Atlantic and Gulf coasts will keep moderate to fresh northeast breezes across Florida Keys waters.
The second issue will be a cold front moving through the area Wednesday morning, which will bring gusty north winds and low clouds. Not to mention, the low level jet will be increasing. /issued 225 PM CDT TUE OCT 11 2016/ A cold front will arrive Wednesday around sunrise to northwest Oklahoma and bring low clouds and gusty north winds along with drier and cooler air.
1038 PM EDT Tue Oct 11 2016 High pressure will slide off the New England coast overnight.
Soak in all that great mid October warmth in place today, with big changes lurking just to our west in the wake of a cold front draped from across central MN down into northeast KS at mid afternoon. That boundary is just waiting for a digging upper trough through the northern Plains to give it a kick eastward heading into the night, with the surface boundary expected to be clearing the eastern CWA just after sunrise. Things change quickly Wednesday evening and night with quite the push of drier air and subsidence overtaking the area as low level ridging parks directly overhead. Given the cool start and incoming much drier air/light winds, don't see why we won't bottom out into the 20s and lower 30s pretty much everywhere, even in the typically warmer Mississippi River valley.
722 PM EDT TUE OCT 11 2016 Aviation Fair weather will continue tonight before a cold front brings rain and a few thunderstorms Wednesday and Wednesday night.
746 PM EDT Tue Oct 11 2016 A large high pressure system will maintain control of our weather through Wednesday.
Tonight's main concerns will be very cold temps and areas of patchy freezing fog. This melting could cause refreezing and black ice across area roads tonight. areas of freezing fog will be possible.

The second issue will be a cold front moving through the area Wednesday morning, which will bring gusty north winds and low clouds. /issued 225 PM CDT TUE OCT 11 2016/ A cold front will arrive Wednesday around sunrise to northwest Oklahoma and bring low clouds and gusty north winds along with drier and cooler air.
930 PM EDT TUE OCT 11 2016 Evening soundings show a sharp H85-H70 subsidence inversion over the FL peninsula thanks to a strong high pres ridge spanning the ern seaboard. Anticyclonic flow around the leading flank of the ridge will generate a steady NE flow overnight. The high surf will maintain the risk of additional beach erosion near high tide, listed below.
Comfortable conditions are again expected overnight with low temperatures falling into the lower 60s across the Nature Coast, and mid to upper 60s central and south.
748 PM EDT TUE OCT 11 2016 Dry and cool high pressure will ridge southward and into the forecast area through Wednesday.
