(Today through Monday) Through Monday, the flow pattern aloft remains zonal around broad ridging across the southern Gulf of Mexico. Monday, a low and associated cold front will move across the Ohio River Valley, with high pressure becoming centered to our east.
939 AM EST Sun Mar 5 2023 A weak boundary will pass through today before high pressure returns tonight into Monday.
539 AM CST Sun Mar 5 2023 (Today through Monday) A broad area of high pressure extends from Iowa/Minnesota southeastward toward the Midwest with our area enjoying the benefits of that. Tonight will be warmer as surface winds pick up a southerly component and remain around 5 mph through the night. Monday will be warmer with a few locations approaching 80 degrees. (Monday Night through next Sunday) The cold front will move through Monday night with winds turning out of the north.
536 AM CST Sun Mar 5 2023 After some early morning clouds in response to warm advection aloft, sunshine and a much warmer and windy day is on tap with increasing southerly surface flow to the east of the lee side trof. While cooler, temperatures will remain mild and above climo on Monday with better cooling expected Monday night.
Drier and cooler through midweek. With lows in the upper 20s and lower 30s this morning there could be a bit of freezing fog on some surfaces possible. Warmer today with the high pressure moving in and increased solar insolation, highs today will get to the mid 40s and lower 50s.
555 AM CST Sun Mar 5 2023 (Today through Monday) Through Monday, the flow pattern aloft remains zonal around broad ridging across the southern Gulf of Mexico. Monday, a low and associated cold front will move across the Ohio River Valley, with high pressure becoming centered to our east.
PWATs will gradually increase throughout the night tonight before increasing to over 1" tomorrow as a warmer and more moist airmass gets advected into South Texas. Temperatures today are expected to remain warm topping out near 88 degrees across the Brush Country before climbing into the lower 90s tomorrow. Overnight lows tonight will remain mild with temperatures ranging from the lower to upper 60s.
There are some of the ensembles, specifically the HREF, that have a line of persistent freezing rain along a frontal boundary from Jackson to Ludington as the system moves in Monday morning. What consensus there is is that there will be decent QPF with this system with the higher amounts coming in two different periods. As the low exists there is a chance of a bullseye of QPF on the backside of an upper level trough swinging through behind the low.
956 AM EST Sun Mar 5 2023 Dry high pressure will cover the region through Monday.
Issued by National Weather Service Little Rock AR 527 AM CST Sun Mar 5 2023 With high pressure to the east of the Mid-South, dry and warmer weather is in store for today and Monday. A cold front will move through the region from the north Monday night.
523 AM EST Sun Mar 5 2023 Dry high pressure will cover the region through Monday.
(This evening through Monday) A zonal flow aloft prevails over the region with a broad low- amplitude longwave ridge axis just to our east. The broad longwave ridge axis will continue to move further east of the area this afternoon but dry air in the mid and lower levels will keep skies sunny areawide. Highs will range from the lower 70s far north and in the higher terrain far east to near 80 generally south of the U. A few clouds may move in from the east after midnight as the low-level easterly flow becomes better established with time. While the low and mid levels will be gradually moistening, dry conditions are expected through the afternoon. Highs will range from the mid 70s far north and across the higher elevations east to readings in the lower 80s south.
1117 AM CST Sun Mar 5 2023 (Today through Monday afternoon) If you are a fan of warm weather, the next couple of days are for you! Zonal flow aloft will persist through tomorrow with steadily rising heights along with a strengthening low level thermal ridge. Today we will see 850 hpa temps approaching 19C- 20C, resulting in highs in the lower 80s across much of the region.
1233 PM CST Sun Mar 5 2023 Latest surface analysis was showing that the cold front has moved down to near I-70 at this hour with light winds across Missouri and Illinois. Highs today will climb into the lower-mid 60s as 850mb temperatures climb into the 5-10C range with a partly cloudy sky. A upper low over the Pacific Northwest will eventually move east this week, with the GFS digging a deeper trough over the Rockies by midweek compared to the more consistent ECMWF and Canadian which show a more progressive upper low moving across the Midwest late this week.
This evening winds become light and variable and ensemble guidance favors some fog development again overnight into Monday morning across the favored interior locations, however with a bit more cloud cover and temps a few degrees warmer it shouldn't be as widespread as it was this morning. Low temps tonight will range from the lower 60s inland to around 70 near the coasts. The Naples area which definitely could use some beneficial rainfall unfortunately has the lowest PoPs across the forecast area.
RH values are currently in the low to upper 20s for most areas. Tomorrow, high pressure shifts east and we see a return flow out of the southwest. Discussion: A building ridge this week will continue to moderate the weather.
Temperatures along the island chain have already reached the lower 80s, and with dewpoints in the lower 70s, it feels quite muggy for this time of year.
These west winds have allowed temperatures to soar well into the 70s and into the lower 80s in a few locations.
A weak wavy cold front has stalled across southern portions of the forecast area and has become increasingly diffuse as it slowly lingers in the area.
302 PM EST Sun Mar 5 2023 (This afternoon through Monday) High pressure remains firmly in place across the area, bringing sunshine and comfortable weather for the entire CWA. Highs today and tomorrow will be in the low to mid 70s across the area, with mid 60s across much of northern GA. Overnight lows will be mostly seasonal in the mid to low 40s with the cooler temps in the higher elevations of the GA mountains.
327 PM EST Sun Mar 5 2023 High pressure will move off to the east tonight. A cold front will approach from the west on Monday and cross the area Monday night. High pressure will then build in through midweek. Ridge of high pressure extending south across the area will translate eastward overnight. This will result in winds picking up in the latter half of the night in western counties, so lows will be warmer there than in the east. A weak disturbance will track across the lower Great Lakes late tonight.
133 PM EST Sun Mar 5 2023 Dry high pressure will cover the region through Monday.
1124 AM CST Sun Mar 5 2023 (Today through Monday) A broad area of high pressure extends from Iowa/Minnesota southeastward toward the Midwest with our area enjoying the benefits of that. Tonight will be warmer as surface winds pick up a southerly component and remain around 5 mph through the night. Monday will be warmer with a few locations approaching 80 degrees. (Monday Night through next Sunday) The cold front will move through Monday night with winds turning out of the north.
Near the surface, a lee side trough of low pressure is strengthening in eastern Colorado. Despite a strong zonal flow aloft prevailing across the region, tranquil conditions will persist during the period as an already drier air mass in the lower/mid levels is reinforced by cold/dry air spreading into western Kansas in wake of a cold front pushing through western Kansas late tonight. The lower 40s(F) are still possible in south central Kansas. Look for highs only up into the 50s(F) Monday afternoon across west central and central Kansas with the lower 60s(F) possible farther south along the Oklahoma border.
1102 AM CST Sun Mar 5 2023 (Today through Monday) Through Monday, the flow pattern aloft remains zonal around broad ridging across the southern Gulf of Mexico. Monday, a low and associated cold front will move across the Ohio River Valley, with high pressure becoming centered to our east.
Another system may near the area later in the week with gusty winds and cooler temperatures. Wind gusts have generally been between 40 to 50 mph so far today but a few higher gusts remain possible through this evening for areas to the north and east of the Mogollon Rim, especially in places that are downwind of the higher terrain. With the winds remaining up overnight, temperatures will remain "warmer" and generally in the 20s across higher elevations and 30s to 40s in the lower elevations and valleys.
1258 PM EST Sun Mar 5 2023 A weak disturbance will bring a few rain or snow showers today before high pressure builds into the region late tonight and Monday.
If you have been following along over the past few days, you know there will be a trough parked in the Pacific Northwest most of the week.
Earlier today, a brief cloud line developed over the Lower Keys thanks to the weak northeast flow and the heating of the island chain. Mean-layer ridging centered near Hispaniola has continued to block the stalled front from nearing the Keys.
(This evening through Monday night) A cold front is expected to slip south into the Panhandles late tonight.
The surface pressure gradient will weaken tonight as a low pressure slides east across the northern Texas Panhandle.
1244 PM MST Sun Mar 5 2023 Water vapor shows large upper low/trof over the Pac NW, with next ejecting short wave moving through WY. At the surface, broad low covers the Central Rockies front range with inverted trof extending into the far western Dakotas.
Current surface analysis reveals broad high pressure sprawled out across the Tennessee Valley into the southeastern U. A cold front will approach from the northwest tomorrow, but out ahead of it we'll see gusty southwesterly winds mix down to the surface in the late morning to afternoon hours. ridging will amplify through mid-week as troughing digs from the Rockies into the Plains. Monday evening a cold front will enter the region.
1105 AM CST Sun Mar 5 2023 (Today and tonight) Elongated upper trough will continue to move through the northern Rockies into the northern Plains today and tonight. These south to southwest winds will bring in a warmer airmass from the southwest across Oklahoma today. As the upper wave moves east into the Upper Midwest tonight a cold front will surge south in its wake, moving into northern Oklahoma overnight. This will mark the beginning of a much cooler week ahead.
Highs this afternoon have climbed into the lower to mid 80s across most of the area with gusty south-southwest winds.
(Today and tonight) Key Message: Another quiet weather day expected, with temperatures a bit warmer than yesterday.
1215 PM CST Sun Mar 5 2023 After some early morning clouds in response to warm advection aloft, sunshine and a much warmer and windy day is on tap with increasing southerly surface flow to the east of the lee side trof.

Issued by National Weather Service Little Rock AR 1149 AM CST Sun Mar 5 2023 With high pressure to the east of the Mid-South, dry and warmer weather is in store for today and Monday. A cold front will move through the region from the north Monday night.
High pressure remains in control of the weather across the forecast area today. While a drier airmass remains over us, temperatures will be a bit warmer as they range from the lower 70s to around 80. The prominent subtropical ridge that has been a fixture over the Gulf of Mexico for much of the cool season is forecast to rebuild after being temporarily suppressed. Temperatures this weekend have been closer to climatology, but a surface warm front will approach from the south, and the airmass will modify given plenty of sun.
1223 PM EST Sun Mar 5 2023 High pressure provides dry conditions and light winds today into tonight.
At lower elevations the higher snow accumulations will be focused over Harney and Malheur counties through early afternoon. As the precipitation advances eastward later in the day, warmer surface temperatures will limit snow accumulations along the I-84 corridor. Breezy conditions will keep wind chills at or below freezing across the region today.
Secondary challengeÂ will be the highs on Monday following a cold frontal passage Sunday night. Â Tonight a cold front will cross southwest Kansas and this will bring an end to the springlike temperatures.
*Cooler than average weather persists through midweek, then warmer for the middle to end of the week. Gusty winds are expected to diminish by later this afternoon in the High Desert, with stronger winds continuing through the San Gorgonio Pass and the adjacent mountain slopes through Monday morning. Gradual warming is expected for the middle to end of the week as a low pressure that was hanging out off the coast of the Pacific Northwest finally moves east.
212 PM EST Sun Mar 5 2023 A weak disturbance will bring a few rain or snow showers today before high pressure builds into the region late tonight and Monday.

1242 PM EST Sun Mar 5 2023 High pressure will prevail into tonight. A cold front approaches from the west on Monday and crosses the area Monday night, bringing a chance of a few showers late in the day into Monday evening. High pressure will then build in through midweek offering a period of dry weather. High pressure will predominate through the day. Broad mid level ridge to build over the region tonight with a warm front lifting north into the southern Great Lakes tonight. Expect mainly dry conditions but can not rule out a shower after 06Z across the far north closer to the warm front. Lows to range from the mid/upper 30s northeast to the lower 40s southwest. In WAA pattern have adjusted temperatures slightly above NBM with highs from the mid 60s north to the lower 70s south.
Mostly sunny skies will continue tomorrow along with even warmer temps as surface winds increase from the south. Monday night, we'll get a weak surface front, but this will only bring a few additional clouds and also slightly cooler temperatures going forward.
High pressure over the eastern U. Temperatures in the lower to mid 60s expected to reach the upper 70s to near 80 this afternoon.
Wind remains up tonight, allowing temperatures to remain much warmer than this morning, generally in the 45 to 50 range. This will drag a cold front down across our cwa late afternoon and evening. May see an uptick in moisture in the low levels, but with zonal flow aloft, won't see the column saturate enough to sustain much in the way of precipitation development.
242 PM EST Sun Mar 5 2023 A weak wavy cold front has stalled across southern portions of the forecast area and has become increasingly diffuse as it slowly lingers in the area.
(Tonight) A ridge of high pressure will remain in place across the region tonight. Lows will not be as chilly and several degrees warmer than seasonable values, mainly reaching the upper 40s.
1122 AM CST Sun Mar 5 2023 High pressure remains in control of the weather across the forecast area today. While a drier airmass remains over us, temperatures will be a bit warmer as they range from the lower 70s to around 80. The prominent subtropical ridge that has been a fixture over the Gulf of Mexico for much of the cool season is forecast to rebuild after being temporarily suppressed. Temperatures this weekend have been closer to climatology, but a surface warm front will approach from the south, and the airmass will modify given plenty of sun.
High pressure at the surface will remain wedged into the forecast area from the east as we begin the work week. A stalling frontal boundary to our northwest and increasing southwest flow across the region, will result in warmer and increasingly humid conditions come Monday.
Up to 5 inches of new snow is possible, with the highest amounts along the SD border. This keeps the higher snowfall rates towards our south and towards the west. However, the higher amounts are looking further toward the SD region. It doesn't look like we will fully be able to mix down the highest winds of 35kts for a majority of the area, but the chance is still there (20%) on an isolated basis. This is thanks to the crusted over snowpack in areas from the warmer temperatures melting the top layer of snowpack. Temperatures will be cooler behind the system, with highs Monday only getting into the single digits for eastern ND and lower teens for MN.
Wind speeds will remain elevated tonight along and east of the interstates as a LLJ develops but decrease across the west and northwest within a prefrontal trough. As a result, and with cirrus coverage again expected to increase, overnight low temperatures will remain well above average with dewpoints in the low to upper 40s.
This will result in a warmer night with lows in the mid/upper 50s. Otherwise, most areas will be in the low/mid 80s. The cold front will sag closer to the Red River Monday night, but a generally warm night is expected with most locations in the lower 60s.
Overnight, expect partly cloudy skies and temperatures in the low to mid 70s,while the upper 60s are possible in more sheltered locations. The island chain continues to be between two synoptic features, a decaying trough to the northwest and a ridge to the south, resulting in northeast to east winds up to 10 mph. The KKEY 00z sounding revealed a strong inversion above the 850 MB, and at the low levels, northeast to east winds 5 to 10 knots. Nevertheless, the high pressure and dry air aloft resulted in nil Pops along the island chain, but a few short-lived showers developed in the Straits of Florida.
600 PM CST Sun Mar 5 2023 (Tonight) A ridge of high pressure will remain in place across the region tonight. Lows will not be as chilly and several degrees warmer than seasonable values, mainly reaching the upper 40s.

It was understood those counties were left out due to the lower nature of forecast snowfall, which still appears to be the case.
An upper level trough is over the Pacific Northwest.
A cold front moving southeast across Larimer County this afternoon will push into the Denver area by this evening. On Monday, light snow will continue in the mountains north of Interstate 70 but under more stable conditions with the region under more subsidence with more of a ridge over CO. The lower levels will remain dry with winds transitioning to more east- southeasterly by Monday afternoon. Cooler temperatures return, with highs 40s around Denver, with mid 30s along the northern tier counties. A cooler than normal and fairly moist period of weather can be expected for the CWA this coming week.
