326 PM CDT Thu Mar 16 2017 Skies are partly cloudy across the forecast area this afternoon with temperatures from the lower 40s to lower 50s. High pressure is now east of the region which allowed winds to shift to the south. A warm front will move across the Mid-Mississippi valley overnight. Temperatures will be much milder than this morning with lows Friday morning in the low to mid 40s. On Friday, a cold front will approach the region from the northwest. Temperatures will be much warmer with highs mainly in the 60s. The cold front will move through the region Friday night with more showers and isolated thunderstorms expected mainly during the evening hours.
606 PM EDT Thu Mar 16 2017 Dry weather is expected tonight under high pressure.
The clouds have held temperatures up around the freezing mark, but elsewhere most locations are in the low to mid 20s, if not into the upper teens. Tonight the moisture will increase in the low- levels, as the mid and high moisture moves out of the region. Cannot rule out a sprinkle or two this afternoon and evening, but 00Z NAM and GFS soundings show a deep enough saturated layer in the low-levels to support a chance of light rain/drizzle after midnight. The 00Z guidance continues to develop a lot of convection along and ahead of the cold front Friday evening, mainly over the southern half of the area. Low level moisture return will be limited with surface ridging over much of the Gulf, and lapse rates will not be terribly steep.
Near normal temperatures are ongoing this afternoon with warmer conditions expected tomorrow as clouds mixout through the afternoon. As anticipated, warmer conditions are ongoing this afternoon vs. yesterday given the warmer start this morning thanks to higher low- level moisture shifting in from the south. Atop this moisture, general weak northwest H5 flow is ongoing with a weak high pressure ridge over north Mexico expected to develop into Friday. Low temperatures Friday will be above normal given the supportive floor of the low and mid 60 dewpoints. High temperatures should be near similar to today and perhaps 1-2F degrees warmer.
The drier descending air across the west will allow considerably quick warming today, reaching around 70s degrees most areas behind the trough by noon, and highs by mid afternoon settling in the mid 80s. Highs may only top out in the low 70s farther east where the downslope effect is absent and the air is not as dry. However at the same time, a cold front will be moving through the area from around midnight onward, turning winds northerly. As a cold front moves through the area early Friday morning the cold advection will have a negative effect on the highs for the day.
MVFR and potentially IFR cloud deck will encompass the region overnight ahead of an incoming cold front. The rest of the forecast still appears to be on track with a few areas experiencing a bit of light drizzle with strong southerly winds and warmer conditions. These winds are expected to transport warmer temperatures and also increasing low level moisture back into the region. combined with increasing warm air advection interacting with the higher terrain locations of Southeast Oklahoma could create some patchy areas of light drizzle during the day today.
Will go with a Frost advisory for parts of interior se Ga where temperatures should stay just above freezing. Temperatures will be warmer on Friday with light ne to e winds.
With the extensive cloud cover and southerly winds temperatures will be much warmer than the past couple of nights. We will forecast lows in the mid 30s north to the lower 40s at most locations. Southwest to west winds will bring mild air into the cwa with highs ranging from the lower 50s to lower 60s.
1215 PM CDT Thu Mar 16 2017 Appears that large scale flow is becoming a bit more progressive thanks in part to deepening longwave trof digging off the Canadian west coast. Wv imagery this morning a well amplified ridge extending from the nrn Plain up thru cntrl Canada. Increasing thkns building in from the west will contribute relatively warmer high temps the next several days despite a dry cold front making a push southward into the CWA Thursday night.
340 PM EDT Thu Mar 16 2017 SHORT TERM (Tonight through Friday) After the passage of cold front last night high pressure located off the southeast continues to dominate South Florida weather tonight.
The models have also trended a bit cooler this run, with model soundings indicating less wintry precipitation and more snow across the area tonight. The low pulls out rather quickly on Friday, with only light rain or drizzle in place by the afternoon hours.
The front will drop southward across the region Friday as an upper level trough digs into the Great Lakes region.
136 PM EDT Thu Mar 16 2017 Mainly dry weather is expected this afternoon under building high pressure.
As a result, warm air advection proved to be enough to overcome the abundant cloud cover allowing temperatures to warm well into the 60s and even into the low 70s across some portions of East Texas. In addition, surface dewpoint depressions are still between 8 and 15 degrees F, which suggests the lowest levels of the atmosphere will need to moisten to support drizzle.
255 PM PDT Thu Mar 16 2017 High pressure remains in control over the entire CWA, allowing for another couple days of the early spring like weather along with dry conditions. A pattern change is expected by this weekend as the next system moves in from the Pacific with cooler weather, clouds, and rain.
221 PM EDT Thu Mar 16 2017 Marine High pressure will slide through the region today bringing fair weather and sunny skies. The quiet weather will continue into tonight as the high slips away to the southeast. The light snow will mix with a bit of freezing rain Friday morning as warmer air aloft rides over some residual cold air at the surface.
The high level clouds over Utah now still on track to stream into Colorado this evening allowing for low temps tonight across northern UT and CO to moderate a few degrees as compared to last night. Temperatures on Friday will increase once again as a high pressure axis moves over the region again. The fortunate part with these high daytime temperatures is that at night the low temperatures are cooling enough to slow snowmelt into our streams and rivers.
333 PM EDT Thu Mar 16 2017 Brisk and cold northwest flow pattern, with diminishing lake effect and orographic snow showers will be replaced by high pressure tonight into early Friday.
209 PM MST Thu Mar 16 2017 Highs in the 90s will continue across the lower deserts through the weekend.
After a cold start to the day, temperatures will warm into the low to mid 50s, about 8-10 degrees warmer than yesterday. Moisture return will begin ahead of the next rain system, and overnight lows tonight will be noticeably warmer.
Overall drying weather is expected starting tonight, as upper ridging begins to nose in from the west.
213 PM EDT Thu Mar 16 2017 Canadian high pressure will settle over the area tonight providing another very cold night with a hard freeze expected. Warming temperatures expected on Friday due to a developing southerly flow as the high moves into the Atlantic.
343 PM EDT Thu Mar 16 2017 High pressure will continue moving east this afternoon with slightly warmer southwest winds this afternoon. Another low pressure system will approach late tonight and move across the region on Friday. A wintry mix of snow, sleet and freezing rain is looking likely Friday morning before precipitation changes to all rain as temperatures rise above freezing.
An upper trough will move southeast across the upper Midwest on Friday, with trailing portion of associated cold front moving south across Oklahoma and into northwestern Texas by Friday evening. With weak surface convergence along the dryline and approaching cold front Friday afternoon, along with limited moisture, the chance for any shower/thunderstorm development in our far northern and northwestern counties looks too remote to mention in the forecast. With low-level thermal ridge building into our area from the west, temperatures Friday afternoon will be rather warm with highs expected to be in the mid to upper 80s.
311 PM EDT Thu Mar 16 2017 Low pressure will continue to pull away to the northeast through tonight.
521 PM CDT Thu Mar 16 2017 A dry cold front will move across the OK and TX Panhandles later tonight and Friday morning with cooler temperatures in store Friday afternoon. An upper level ridge of high pressure will dominate the weather across the srn high plains this weekend.
320 PM EDT Thu Mar 16 2017 High pressure will slide off to our southeast tonight as a cold front moves east across the Plains and into the Upper Midwest. Mid level clouds are expected to increase quickly after midnight as a warm front lifts northeast toward the area. Rain chances increase from west to east late Friday morning as the warm front lifts through. However, there remains enough uncertainty on timing and how fast temps in our valleys warm above freezing so will continue to message the possibility of spotty freezing rain Friday morning. Rain will continue into Friday evening then diminish late in the night as the cold front passes through.
400 PM EDT Thu Mar 16 2017 High pressure will slide off to our southeast tonight as a cold front moves east across the Plains and into the Upper Midwest. Mid level clouds are expected to increase quickly after midnight as a warm front lifts northeast toward the area. Rain chances increase from west to east late Friday morning as the warm front lifts through. However, there remains enough uncertainty on timing and how fast temps in our valleys warm above freezing so will continue to message the possibility of spotty freezing rain Friday morning. Rain will continue into Friday evening then diminish late in the night as the cold front passes through.
158 PM EDT Thu Mar 16 2017 High pressure builds across the southeastern states this afternoon.
300 PM EDT Thu Mar 16 2017 Arctic high pressure will extend across central NC through tonight, then drift to our southeast on Friday.
Tonight, a cold front will move through the area with increasing clouds out ahead of it.
340 PM EDT Thu Mar 16 2017 High pressure will gradually slide east of the region overnight, but a mostly clear sky will prevail in most areas. This, combined with the dry air at the surface will allow temperatures to drop well below freezing over much of east Tennessee, southwest Virginia, and southwest North Carolina, In the meantime, clouds will very gradually stream into the region ahead of the next low pressure system. They may make it the Southern Plateau and Valley late tonight, which should help to keep them just above freezing. A cold front will move through the Southern Appalachian Region Friday night for likely to categorical pops.
1255 PM CDT Thu Mar 16 2017 /18Z TAFS/ The low cloud field has eroded across all except some of our eastern and southern counties as of 1245 PM. Cloud ceilings should be mostly in the 1000-2000 ft range, with KSOA on the lower end of this range. /issued 402 AM CDT Thu Mar 16 2017/ (Today and Tonight) A weak ridge aloft will move across the area today. The low level thermal ridge will strengthen across West Texas today and spread east into our area through Friday.
A cold fropa tonight will yield cooler temperatures for Fri with no high impact weather expected.
SHORT TERM (Tonight through Friday Night):Spring time weather continues through the period across Deep South Texas and the Rio Grande Valley as ridging remains in control. Main story for the short term will be the breezy conditions as low pressure develops over the southern Plains. Expect overnight temperatures to be slightly warmer than last night, with lows in the lower to mid 60s. Did go on the warmer side of guidance for highs Friday and bumped temperatures up a degree or so along the Rio Grande out west, where cloud cover may not be as prevalent and winds more moderate.
214 PM MDT Thu Mar 16 2017 20z surface analysis had low near KICR with trough into central WY and cold front into southwest SD into northeast WY. Friday, much cooler day expected. Upper ridge will build over the Rockies and head toward the CWA Friday night.
208 PM EDT Thu Mar 16 2017 High pressure exits tonight.
Winds are light at low levels as strong high pressure is in place. Although low level moisture will be on the increase as noted by dewpoints climbing into the middle 40s tonight and the lower 50s tomorrow, temperatures should quickly fall into the lower to middle 50s both tonight and tomorrow night.
A pacific cold front currently moving through western Montana, as a warm front is pushing through western Nebraska. The upper ridge flattens out across the region as the Pacific cold front advances through northwest South Dakota this afternoon. The Pacific cold front will sweep south and exit the area after midnight. Upper level ridging will dominate the overall weather pattern the next several days across the region. A Pacific cold front will bring cooler and slightly more moist air to the region Friday, which will alleviate the fire danger.
233 PM EDT Thu Mar 16 2017 Canadian high pressure will be centered over the area tonight providing another very cold night with a hard freeze expected. It will be warmer Friday due to a developing southerly flow as the high moves into the Atlantic.
which should allow temps to be a few degrees cooler than Thurs Night. No precip expected during the short term period due to moisture being limited to roughly the lower 100mb.
/Issued 1132 AM EDT Thu Mar 16 2017/ High amplitude long wave trough across the eastern US is slowly pulling away from the local area to the northeast. but the RH values will combine with fuel moistures below 10 percent to warrant the high fire danger. Winds also calming down as the ridge settles over the area. Low-level flow starts turning more west to southwest overnight tonight should keep most areas outside of the higher elevations at or a bit above freezing with highs climbing back up to around normal for Friday. As the associated cold front moves across the CWA, the moisture will diminish as will the showers.
Tonight and Friday Clear and dry conditions this afternoon will give way to snow or a wintry mix overnight into Friday morning before surface temperatures warm above freezing, resulting in a change to rain. Freezing/a mix is possible across northern Wisconsin Friday morning while the rest of the area changes to all rain as temperatures warm.
Temperatures will be a cooler but still well above normal.
322 PM EDT Thu Mar 16 2017 Low pressure will slowly move away to the northeast tonight into tomorrow.
A cold front will push south tonight, however this front will be Pacific in nature, and hence downslope momentum will be fairly substantial behind it. Temperatures should top out from the upper 60s to lower 70s, which is the higher end of most guidance, and justified given our very dry conditions.
as well as turning toward more rain vs freezing rain through midnight. Updated forecast to add more freezing precip for tonight. Water vapor loop indicated an upper level ridge over the western Dakotas with an upstream trough over the Pacific Northwest. Pacific Northwest trough will move through the Northern Plains Fri. Trough is forecast to intensify after it moves away from the area. Wind shift moves through Thu night and cold front to follow on Fri. Water vapor loop indicated more troughs in the Northern Pacific which will approach the area at the end of this period/12Z Sun. Could see some freezing drizzle over parts of the southwest and northwest this morning.
Dry and benign weather expected to continue late this week as a low amplitude ridge axis moves eastward into the Great Plains today. Models do show a weak cold front moving into Wyoming this afternoon. It will be noticeably more windy today ahead of the cold front. Friday will be slightly cooler across most of the area as the cold front moves southeast.
312 PM CDT Thu Mar 16 2017 High pressure forecast to continue shifting to the east of the area.
Neutral/weak cold advection will have little influence on the regions temperatures for Friday, however northwest low level flow will favor better mixing conditions so highs will be a tad milder across the area with snow cover while cooler for southwest counties.
1259 PM MDT Thu Mar 16 2017 Early morning WV imagery and RAP analysis shows ridge centered over our CWA. At the surface a warm front is in the process of moving our our CWA with lee trough just east of CO border (closed center in SE CO). Low level moisture has increased ahead of warm front where there is southerly flow in our east. This low level moisture could support patchy fog development early this morning.
Forecast soundings remain rather dry in the lower levels through the afternoon, with only a pinch of moisture around 4,000 feet. As for temps today, with strong WAA expected, have trended aoa the warmer guidance despite expected cloud cover. Tilly Cold front to move southeast through forecast area on Friday, exiting by Friday evening.
Forecast soundings start to moisten up in the lower levels late evening, which will increase the chances of showers. Geelhart Showers and isolated thunderstorms will come to an end Friday night as high pressure starts to build into the region.
Low clouds and fog will likely remain in place until a mild cold front moves across Oklahoma during the day Friday.
An area of low pressure will move through southern Manitoba tonight, reaching northwest Ontario on Friday. Meanwhile, an upper level trof will close off into an upper low by Friday afternoon. As temps cool this evening, the rain will mix with snow, or just turn into freezing rain, then become all snow later this evening and overnight. Freezing rain is still possible for a time overnight as there will be just enough warm air just above the surface to melt the snow as it falls and turn it to freezing rain. A light glaze of ice is anticipated where freezing rain occurs. Confidence is low in the freezing rain and the amount of ice it may produce.
Temperatures will be a little warmer tonight, but still cool with lows ranging from the mid to upper 30s over much of interior southwest and south central Alabama and the northwest Florida Panhandle, with readings around 40 to the lower 40s near the beaches and farther west across southeast MS. Mostly to partly sunny skies and warmer temperatures are anticipated Friday as a more pronounced southerly low level flow becomes established over the region. Highs are expected to range from the upper 60s near the beaches/immediate coast to the lower 70s inland.
255 PM EDT Thu Mar 16 2017 Dry weather is expected tonight under high pressure.
A weak cold front will stall over central Utah this afternoon.
High pressure moving by to the north will provide a dry air mass with veering winds. High pressure centered on the Gulf coast this morning will dominate with a cool dry northeasterly to northerly low level flow. High pressure dominates today with northeast to north winds at 15 knots or less.
Main challenge is how much precip will be behind wind shift/trough as temps begin to decline. for an all rain solution but 12Z GFS/GEM/NAM and late morning Hi Res runs slowed precip over NW Minnesota down sufficiently that sfc temps may fall to or just below the freezing mark. Thus, in the 06Z to 12Z timeframe we still have a mention of a wintry mix however would expect rain/light freezing rain to change over to snow/drizzle/freezing drizzle rather quickly.
211 PM EDT Thu Mar 16 2017 Hydro High pressure will slide through the region today bringing fair weather and sunny skies. The quiet weather will continue into tonight as the high slips away to the southeast. The light snow will mix with a bit of freezing rain Friday morning as warmer air aloft rides over some residual cold air at the surface.
256 PM PDT Thu Mar 16 2017 High pressure will continue to provide dry conditions and above normal temperatures through Friday.
Cold front moved through the entire area by 15Z and was followed by 3 hour pressure rises in the 2-3 mb range, as well as deep mixing, which created wind gusts in the 25 to 35 mph range.
Somewhat cooler max temps expected, although temps will still be running ~15F above normal for this time of the year. We will see more clouds tomorrow, especially over the higher terrain.
229 PM CDT Thu Mar 16 2017 Closed low. mature cyclone. Upper ridge building into the Missouri River Valley northwest into central Canada and the western Hudson Bay. Closed low over the Gulf of Alaska with waves coming onshore in the Pacific Northwest. In the near term a Pacific cold front will move across western Nebraska tonight. Cooler air moving in on Friday with temperatures still above normals. Boundary layer remains mixed and temperatures hold in the 20s and 30s as warmer under the ridge moves east. Warmer air aloft.
547 PM CDT Thu Mar 16 2017 H5 ridging will move across the Northern Plains tonight with a warm nose of +4 to +12C at H85 pushing into the CWA. Some of that warming will go to continuing to melt snow but that coupled with cloud cover will help keep temps at or above freezing in most areas tonight. Right on the heels of this ridge is a cold front from an associated low crossing Saskatchewan and Manitoba. Brisk winds will continue much of Friday night within cold advection and tight gradient on southwest flank of deepening low pressure over the Great Lakes.
208 PM EDT Thu Mar 16 2017 Brisk and cold northwest flow pattern, with diminishing lake effect and orographic snow showers will be replaced by high pressure tonight into early Friday.
656 PM EDT Thu Mar 16 2017 An approaching cold front is expected to cause a mix of snow, sleet, and freezing rain across our area late tonight and Friday morning with just some light rain or drizzle in the afternoon as temperatures rise above freezing.
As this band heads east, it will encounter drier and cooler air and may be mainly snow until warmer air aloft moves in later this evening. At that point precip may turn to rain or freezing rain, depending on the thermal profile. Due to the light amounts and the possibility of precip becoming plain rain, decided against an advisory for now but travel problems could result if it is predominately freezing rain. Initially we have colder air filtering in behind the departing cold front into Friday night on gusty northwest winds.
Winds will increase even more behind a cold front at all sites after sunrise. /Issued 521 PM CDT Thu Mar 16 2017/ A dry cold front will move across the OK and TX Panhandles later tonight and Friday morning with cooler temperatures in store Friday afternoon. An upper level ridge of high pressure will dominate the weather across the srn high plains this weekend.
Ridge of high pressure currently over central Illinois will shift eastward into the Ohio River Valley today, allowing southerly flow to develop across the region. High temperatures will climb into the lower to middle 40s. Cold front will push through central and southeast Illinois on Friday, accompanied by scattered showers and perhaps a few thunderstorms. High temperatures will climb well into the 50s, with readings reaching the lower 60s across the S/SW. Once the front passes, any lingering showers will come to an end south of I-70 by Friday evening, followed by cooler/drier weather across the board through the upcoming weekend.
Otherwise, low pressure moving into the Plains will increase south winds today. Clouds will limit the warmup somewhat, but most areas will be milder/warmer today. Fri-Fri night: A cold front will move through the area Fri-Fri evening. Sat: High pressure builds in behind the front with a dry air mass.
Forecast soundings start to moisten up in the lower levels late evening, which will increase the chances of showers. Geelhart Cold front to move southeast through forecast area on Friday, exiting by Friday evening.
