836 AM EST Sun Feb 18 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
625 AM EST Sun Feb 18 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
504 AM CST Sun Feb 18 2024 (Today through Monday) Temperatures will be a bit warmer today with highs as the sunshine allows for highs to reach to near 60. High pressure will remain in control during the short term period. Clear skies and dry air will lead to cooler temperatures again tonight, with lows in the mid 30s to low 40s. Once again, there could be a few locations that will approach freezing, so please take the time to protect your at risk people, pets, and plants.
After a cold start to the day, temperatures will climb into the lower to mid 50s for highs this afternoon, with mostly sunny skies.
Precipitation type is primarily expected to be snowfall, though a wintry mix of light freezing rain and snow is possible through the lower valleys of north central Idaho this morning before surface temperatures warm. A very brief ridge of high pressure will build in tonight into Monday morning before another weak disturbance moves into the region Monday afternoon and evening. One thing to watch closely is where does the main energy of the trough go. troughs to dig into the Desert Southwest with lesser impacts in our part of the world. Winds will be increasing on ridge tops from the west up to 25 kts.
Today - Monday: A glancing pass from a weak cold front will keep breezy winds in Minnesota this morning, with some low clouds liable of squeezing out some flurries near Lake of the Woods region. A small low pressure system will pass innocuously through South Dakota Monday helping shift winds out of the east, with mostly clear skies over most of the area save some higher level clouds near the South Dakota border.
509 AM CST Sun Feb 18 2024 (Today through Monday) A surface cold front and a 500 mb trough have pushed east of the BRO CWFA, leaving dry weather and some cloudiness behind. Finally, with improving, but still elevated, winds and seas courtesy of the passage of the cold front, a High Risk of rip currents will exist at the local beaches until around sunset today.
Temperatures warm today into the 40s and 50s as an upper level thermal ridge pushes in across the southern and western CWA. Warmest temperatures will be across southwest Nebraska, kept temperatures trending a little cooler across the northern portion of the forecast area as there is still some lingering snow pack that will keep temperatures a little cooler. Could again see some elevated fire weather concerns for fire weather zones 210 and 219, although min RH will not be as low, around 30 to 35%, the combination of warmer temperatures, drier conditions and breezy winds may lead to elevated concerns. An Upper Level ridge builds in from the west into the High Plains.
Valley temperatures north of I-80 remain near or below freezing, and will likely see precip initially fall as snow across these areas before the column warms, allowing for a changeover to rain along the valley floors by mid morning. Mid level ridging will temporarily amplify across the region tonight into early Monday, before shifting east as an upper low approaches the Pacific Northwest coast. As this ridge axis passes east, southerly winds will increase across the western valleys, and may approach advisory criteria across west central and southwest Utah. Better mixing with this increased flow coupled with 700mb temps near -2C will allow temps to trend roughly 5 degrees warmer across northern valleys, topping out in the low to mid 50s along the Wasatch Front, while temps across southern Utah remain near persistance.
Near freezing temps have settled over the northern and eastern two-thirds of South Central TX, so the min temp forecasts should be in good shape, but areas around Eagle Pass may wind up remaining about 5-7 degrees warmer than the min temp forecast. Only an isolated pocket of freezing temps are forecast tonight, only barely reaching 32, but lows should still be in the 30s almost area-wide.
206 AM MST Sun Feb 18 2024 Today through Monday night: Mostly clear skies and light winds have allowed for a seasonably cold morning, while there is low confidence (20%) for patchy freezing fog to occur outside of the Malta vicinity. Slightly below freezing highs are likely Monday along and north of the US-2 corridor as a backdoor cold front slips southwest out of Saskatchewan.
This will allow temperatures to fall well below freezing over much of the area. /EC/ Monday through Sunday: Through the period an upper level ridge over most of central CONUS will dominate and keep things very uneventful through the middle of the week.
Satellite trends show this should occur before daylight so the northern most tier of parishes/counties should be capable of at least reaching freezing and maybe a few locations of upper 20s this morning. No freezing temps this morning for areas of the south shore but this should be different tonight as we should strongly decouple with efficient radiative cooling. Several areas of the south shore should fall to just reach the freezing mark tonight/Mon morning and since foliage in these areas are in the beginning stages of bloom, we will be bringing up a freeze warning.
515 AM CST Sun Feb 18 2024 - Near to above normal temperatures will dominate the week ahead, though still some uncertainty how quickly temperatures will warm over the deeper snow cover across the Highway 14 corridor early in the week.
- Calmer winds, mostly sunny skies expected today with temperatures likely (>80%) to rise above freezing for highs statewide.
848 AM EST Sun Feb 18 2024 High pressure will result in dry conditions across the area through the early part of the week.
(Now through Monday) The plume of moisture that has extended across much of the Gulf of Mexico the past couple of days will continue to shift further away to the south and east of our region today as an upper level trough and weak upper level low pressure system digs from the Lower Mississippi Valley into adjacent portions of MS/AL. We may see some mid level clouds come in along the base of the upper trough this afternoon into early this evening. Highs on Monday will trend a few degrees warmer with readings mostly ranging from around 60 degrees to the lower 60s.
(Today through Monday) After a cold start to the day, high clouds will continue to clear out as high pressure builds in. Moderation continues on Monday with the high pressure over the area.
This will bring southerly winds with warmer temperatures moving in allowing for highs to be in the 50s and even some spots to the lower 60s. Any residual snowpack in the north should melt with these highs, and the impacts of snow on the ground should be negligible to the high temperatures. Upper high will build further over the Panhandles bringing higher thicknesses our way and fairly light winds with mostly clear skies on Monday.
Northwest Minnesota however looks to stay cooler with temperatures remaining below freezing. Today - Monday: A glancing pass from a weak cold front will keep breezy winds in Minnesota this morning, with some low clouds liable of squeezing out some flurries near Lake of the Woods region. A small low pressure system will pass innocuously through South Dakota Monday helping shift winds out of the east, with mostly clear skies over most of the area save some higher level clouds near the South Dakota border.
Another system will bring warmer temperatures Monday with additional chances for precipitation. Deep southerly flow will bring increasingly mild temperatures (Highs in the low 40s) Monday.
We'll start the day today with temperatures in the lower and middle 20s and wind chills in the teens. Sunny skies today will help get highs into the lower 40s for most of the area. Similar to yesterday, temperatures are expected to remain a few degrees cooler in our south with the snowpack in place.
/Issued 1145 PM CST Sat Feb 17 2024/ /Sunday and Monday/ High pressure will dominate the weather pattern through the short term forecast period. The passage of the trough should be largely inconsequential due to dry sub-cloud air preventing any precipitation from reaching the surface. The high pressure center is currently analyzed just to our west and will move through North and Central Texas this morning. The cool airmass will start to modify today, allowing temperatures this afternoon to climb 5-15 degrees warmer than yesterday but still 10-15 degrees below normal with highs in the 50s.
324 AM CST Sun Feb 18 2024 - Calmer winds, mostly sunny skies expected today with temperatures likely (>80%) to rise above freezing for highs statewide.
751 AM EST Sun Feb 18 2024 Low pressure passes well to the north today and tonight, sending a weakening cold front into the region early Monday.
(Today through Monday) Temperatures will be a bit warmer today with highs as the sunshine allows for highs to reach to near 60. High pressure will remain in control during the short term period. Clear skies and dry air will lead to cooler temperatures again tonight, with lows in the mid 30s to low 40s. Once again, there could be a few locations that will approach freezing, so please take the time to protect your at risk people, pets, and plants.
Updated Aviation Discussion High pressure will hold steady over the region through the middle of the week supporting a continuation of above normal temperatures and dry conditions.
Temperatures are warming slowly through the upper 20s into the lower 30s at this hour, with afternoon highs in the upper 40s to around 50 still expected.
548 AM EST Sun Feb 18 2024 High pressure will result in dry conditions across the area through the early part of the week.
Higher terrain in the Madison, Gallatin, Tobacco Root, Bridger and Little/Big Belt ranges have the highest probability (60- 80%) of receiving snowfall accumulations in excess of 1 inch with as much as 3 inches possible (30-50%) above 7000ft in the Little Belt, Big Belt and Tobacco Root mountains.
327 AM CST Sun Feb 18 2024 - Near to above normal temperatures will dominate the week ahead, though still some uncertainty how quickly temperatures will warm over the deeper snow cover across the Highway 14 corridor early in the week.
Northerly winds will remain elevated between 7-13 knots today, with the highest speeds expected near the coast. (Now through Monday) The plume of moisture that has extended across much of the Gulf of Mexico the past couple of days will continue to shift further away to the south and east of our region today as an upper level trough and weak upper level low pressure system digs from the Lower Mississippi Valley into adjacent portions of MS/AL. We may see some mid level clouds come in along the base of the upper trough this afternoon into early this evening. Highs on Monday will trend a few degrees warmer with readings mostly ranging from around 60 degrees to the lower 60s.
521 AM CST Sun Feb 18 2024 (Today through Monday) After a cold start to the day, high clouds will continue to clear out as high pressure builds in. Moderation continues on Monday with the high pressure over the area.
A series of upper level disturbances rotating around a broad trough of low pressure along the West Coast will produce periods of showers through midweek. Weak upper ridging will lead to a drying trend late in the week.
910 AM EST Sun Feb 18 2024 Low pressure passes well to the north today and tonight, sending a weakening cold front into the region early Monday.
632 AM EST Sun Feb 18 2024 (Today through Monday) An approaching cold front will drive an increase in shower and thunderstorm chances early this morning. A few showers will be possible on Monday on the backside of the low, but most of the day should remain dry - especially the latter half of Monday. Highs should generally reach the lower 70s for southeast portions of the area but could remain in the 60s for northern and southwest portions of the area.
/NEW/ Update: All of North and Central Texas has fallen to or below freezing. Plentiful insolation and dry air will allow for temperatures to quickly rise above freezing this morning, with even the coldest locations rising to the mid 30s by 10 AM. Bonnette Previous Discussion: /Sunday and Monday/ High pressure will dominate the weather pattern through the short term forecast period. The passage of the trough should be largely inconsequential due to dry sub-cloud air preventing any precipitation from reaching the surface. The high pressure center is currently analyzed just to our west and will move through North and Central Texas this morning. The cool airmass will start to modify today, allowing temperatures this afternoon to climb 5-15 degrees warmer than yesterday but still 10-15 degrees below normal with highs in the 50s.
Higher terrain in the Madison, Gallatin, Tobacco Root, Bridger and Little/Big Belt ranges have the highest probability (60-80%) of receiving snowfall accumulations in excess of 1 inch with as much as 3 inches possible (30-50%) above 7000ft in the Little Belt, Big Belt and Tobacco Root mountains.
(This evening through Monday Night) High pressure has taken control of our weather with clear skies, light winds, and dry conditions. Lows will again get down to near freezing for areas north of the Houston Metro with the Piney Woods area possibly getting into the upper 20s. The high pressure over the region today will begin to slide eastwards tomorrow. Afternoon high temperatures will rise into the low to mid 60s. The southerly flow will continue to work its magic Monday night with overnight low temperatures in the low to mid 40s - about a 10 degree change from tonight's expected lows.
247 PM EST Sun Feb 18 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
1221 PM EST Sun Feb 18 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
The approach of this wave has led to subtle lee troughing in E CO, driving light southwesterly winds in the Panhandles.
Tonight Through Monday Night: A weak and moisture starved upper level trough will swing through the region tonight and Monday morning. No precipitation is expected with the trough, but it should increase mid level cloud cover tonight and Monday morning. Though pressure gradients in the lee of the Appalachians aren't overly strong with the high, they my be sufficient to push a weak wedge front into northeast Georgia Monday. Weak upper level ridging and the return of sunny skies should help temperatures trend upward Monday afternoon.
1122 AM CST Sun Feb 18 2024 - Near to above normal temperatures will dominate the week ahead, though still some uncertainty how quickly temperatures will warm over the deeper snow cover across the Highway 14 corridor early in the week.
225 PM CST Sun Feb 18 2024 - Quiet, warmer than normal weather to continue. This melting is ongoing despite temperatures that are generally in the low to mid 30s across the MPX coverage area, with the mid February sun angle (roughly equivalent to mid- October) beginning to work in earnest.
With westerly winds around 10 mph continuing through the night temperatures will be much milder only dropping into the lower to mid 30s. Despite the northerly winds, temperatures will warm back above normal as thicknesses increase with upper-level ridging building over the forecast area once again.
These clear skies will be with us for Washington's Birthday tomorrow and temperatures will run about 8 degrees warmer than today.
Hourly temps running a few degrees cooler than forecast so made adjustments to match up with obs. Dewpoints are running a few degrees cooler as well. Sunny and warmer today along with low RH values.
1102 AM CST Sun Feb 18 2024 (Today through Monday) After a cold start to the day, high clouds will continue to clear out as high pressure builds in. Moderation continues on Monday with the high pressure over the area.
Now with some mixing, that layer is breaking up, and subsidence in the wake of the main trough axis should prevail over the region today. Models show isentropic descent through this layer which gives some confidence in drier mixing, so have nudged dew points toward the lower values of guidance. This will allow temperatures to fall well below freezing over much of the area. /EC/ Monday through Sunday: Through the period an upper level ridge over most of central CONUS will dominate and keep things very uneventful through the middle of the week.
307 PM EST Sun Feb 18 2024 Low pressure will pass offshore of the Southeast U.
248 PM CST Sun Feb 18 2024 - Above normal temps through the middle of the week with highs ranging from the low 40s to 50s. Issued 245 PM CST Sun Feb 18 2024 Tonight through Monday night: A fairly quiet stretch of weather expected tonight through Monday with high pressure building across the Upper Great Lakes. Broad area of high pressure will gradually slide toward the Eastern Great Lakes through the day Monday and southerly flow will increase across WI. However areas with lingering, deeper snow cover across the northeastern CWA (Fond du Lac, Sheboygan, Ozaukee, and Washington counties) may end up a few degrees cooler with highs closer to 40F if not just below. Overnight temps will trend warmer as well with the persisting southerly flow with lows in the the upper 20s to low 30s.
Through the time period an upper trof remains anchored over southeast Canada, with a disjointed ridge over the western CONUS.
With the development of the passing low pressure, there could be several hours of rainfall to go today. Temperatures have made it into at least the lower 70s across most of the area with some mid to upper 70s sneaking into southern Miami-Dade County where the environment is slightly more favorable for more stout convection. Depending on the track of the low, the wind could be strong enough to warrant the consideration of a Wind Advisory for portions of the area on Monday.
Dry and warmer tomorrow with light winds along with low afternoon RH. Tonight, upper trough continues to push further northeast as high pressure builds in from the southwest. High pressure in place across our area tomorrow. Warmer temps, clear skies, and light winds are expected.
112 PM EST Sun Feb 18 2024 Breezy today before high pressure builds into the new work week, with a warming trend. Channeled flow between high pressure across the Southern Plains and low pressure tracking south of James Bay will yield breezy conditions today with sustained winds 8-15 mph and gusts 20-30 mph, highest across the north this afternoon. Warm advection in southwesterly flow will yield daytime highs in the low 40s across much of the lower elevations despite starting out in the teens and lower 20s this morning. Gradients fade this evening as the aforementioned area of high pressure sinks into the Deep South concurrently with the area of low pressure moving off into the Canadian Maritimes.
Other than shifting a cooler airmass currently over the southeastern quarter of the Conus (1000-500mb thickness minimums currently over the Lower Mississippi River shift to over the East Coast by Monday evening), nothing other than the beginning of a warmup in temperatures is expected beginning Monday. Before the warmup begins Monday, a cooler night is in store for the forecast area tonight, with lighter winds and a dry airmass. Winds are still expected to be strong enough for some mixing overnight (around 5 knots or so), so have went on the higher side of MOS. Am expecting temperatures tonight to drop to below freezing over the majority of the forecast area, except for mid/upper 30s along the coast. For Monday, temperatures are expected to top out in the low 60s over the majority of the forecast area.
Temperatures in the mid to upper 40s late this morning expected to rise into the lower/mid 50s this afternoon.
A cold front is on the doorstep of the Florida Keys this morning. Scattered showers ahead of this line crossed through portions of the Lower Keys this morning with diminishing coverage now. Despite a blanket of stratus cloud cover over most of our CWA, temperatures along the island chain are generally in the mid to upper 70s with the only exceptions being in the northern Upper Keys in the lower 70s where the edge of the cold front had been analyzed. The line of showers approaching from the Gulf is expected to reach the Lower Keys early this afternoon (shortly after 18z) and then lumber across the island chain through the evening hours. From synopsis, strong southwest breezes will develop today, as a cold front approaches the Florida Keys coastal waters.
1252 PM EST Sun Feb 18 2024 High pressure will result in dry conditions across the area through the early part of the week.
Temperatures have steadily climbed into the 40s through the morning and should top out in the low 50s this afternoon. Some passing high clouds are expected tonight, and we'll be about 10 degrees warmer overnight although it will still be seasonably cold with temperatures in the low/mid 30s. Some areas east of I-35 will still drop to freezing where winds are lighter. Monday will feature increasing heights aloft indicative of strengthening mid level ridging. This will eventually lead to much warmer than normal temperatures through the middle part of the week.
Lows will be noticeably warmer than this morning's.
325 PM EST Sun Feb 18 2024 Low pressure passes well to the north tonight, sending a weakening cold front into the region early Monday.
With decent ridge/valley splits, some valleys may wind up cooler tonight than they were this past night. Mountain lows in the teens and lower elevation lows in the low to mid-20s are expected, with sheltered valleys likely 5-10 degrees cooler than surrounding ridges.
(This afternoon through Monday night) WV imagery shows dirty ridging over the western CONUS, leaving West Texas under dry, northwest flow aloft.
135 PM CST Sun Feb 18 2024 - Steadily warmer temperatures are forecast through the middle of the week.
(Tonight through Monday night) High pressure centered over Texas will broaden and shift slowly east. Mid-level ridging upstream will build toward West Texas. North winds will shift to light south overnight as high pressure reorients. Temperatures will start out cooler than normal tonight (by 10 degrees), but after tonight the trend will be warmer. Lows tonight will be in the upper 30s across the northern Ranchlands and Brush Country to the mid 40s for the Lower RGV. Temps Monday night will be near normal again; upper 40s across the northern Ranchlands and Brush Country to the mid 50s for the Lower RGV.
- Near to above normal temperatures will dominate the week ahead, though still some uncertainty how quickly temperatures will warm over the deeper snow cover across the Highway 14 corridor early in the week.
High pressure will hold steady over the region through the middle of the week supporting a continuation of above normal temperatures and dry conditions.
1036 AM CST Sun Feb 18 2024 A 1028 mb ridge of high pressure resulted in very cold temperatures in the teens and 20s across the Mid-South early this morning.
Dry conditions in the lower and middle levels are resulting in only some high clouds. Highs will range from the upper 50s north to the low 60s far south.
1106 AM CST Sun Feb 18 2024 A 1028 mb ridge of high pressure resulted in very cold temperatures in the teens and 20s across the Mid-South early this morning.
251 PM EST Sun Feb 18 2024 Weak surface ridging persists today, with strong high pressure building down the East Coast beginning Monday. At the surface, weak ridging persists, with very dry low levels and no rain chances. Lows will be near to a few degrees below freezing for most early Monday morning, with the surface airmass likely too dry for event ground fog formation. Temps near normal/upper 50s for most, but cooler for Northern OBX/Albemarle Sound area with CAA coming off the chilly waters. This low will remain well offshore, reaching our latitude Tues night.
