509 PM EDT MON MAY 30 2016 A weak cold front will push east of Pennsylvania tonight. A ridge of high pressure will build east into the region for midweek. A slow moving cold front will likely push into the region from the Great Lakes by late in the week. Previous: Weak cold front pushing into central PA at mid afternoon, providing sufficient moisture convergence and llvl lift to overcome weak CIN and maintain a line of isolated to scattered convection. Latest hi res cams track broken line of convection out of the Central Mountains and Laurel Highlands by 21z, and the Lower Susq River Valley by 04z late this evening. Lows will range from near 50F northwest to the lower 60s southeast. Slowly rising heights aloft and sfc ridging will provide a mostly sunny and warm day to PA on Tuesday.

Mostly dry and unseasonably warm conditions are in store for northwest California for at least the next several days due to a persistent upper level ridge. As for shower chances, the persistent ridge will likely preclude any substantial activity for the remainder of the work week.
353 PM EDT MON MAY 30 2016 A weak cold front continues to move southeast and is slowly moving into VA and East TN. This evening through tonight, the sfc and mid level ridge will build into the region and cu should dissipate leading to clearing. Drier air continues to mix down as well as advect in from the north, and lows tonight should average a few degrees cooler than this morning, especially in valley locations. For Tuesday into Tuesday night, ridging should continue to dominate although a mid level trough and cold front will begin to approach late in the period and mid and high level moisture should begin to increase late as well.
Isolated to scattered showers and a few thunderstorms have developed over the the high country this afternoon. The bulk of the shower activity has formed on the northern flank of a nearly stationary area of low pressure over southwestern AZ.
Band of showers/isold storms still possible in the mid-afternoon as nose of H850 theta-e ridge expands north. The lowest FFG are for the valley and northeastern ND, thus reduced weather story flash flooding risk from moderate to low.
305 PM EDT MON MAY 30 2016 A weak cold front will enter the region from the west tonight and stall near or just south of the area on Tuesday.
The low level jet will be increasing overhead in the afternoon though, with some lingering warm advection aiding in the development of showers and storms. With the cold front remaining well to the west of the forecast area, temperatures will be warm again Tuesday. Winds will be onshore all day, so it will be cooler near Lake Michigan.

217 PM EDT MON MAY 30 2016 The combination of a trough extending from the remnants of Bonnie, sea breeze boundaries, and diurnal instability will provide isolated to scattered storms this afternoon and evening. High pressure will build to the East Tuesday with the flow becoming more Southerly in the afternoon. Upper ridging will remain over forecast area with sea breezes initiating widely scattered afternoon/evening showers/t-storms. Upper ridge remains over area with sea breezes driving scattered afternoon/evening showers/t-storms Thu-Sat.

A cold front will move east across the Midwest mid-week bringing a chance of showers and thunderstorms. Temperatures will remain above normal ahead of the front with highs in the lower and middle 80s. Despite high pressure over the region today there are a couple minor concerns with forecast. Despite weak cold frontal passage. airmass not much cooler with only slightly lower 925-850mb temps. High pressure at surface will drift east on Tuesday with return flow developing ahead of upper low drifting across the CONUS and Canadian border.
Scattered showers and thunderstorms will continue into evening as the low pressure continues to move across the area. Overnight in the higher terrain there could be some snowfall, which could produce some issues over the Beartooth Pass. Some lingering showers will continues on the backside of the low during the day tomorrow. On top of this temperatures will remain cool across the area, with highs in the low to mid 60s.
Temperatures will be noticeably cooler on Tuesday with northerly flow resulting in highs around 70. A ridge is influencing the CWA for the entire period, yet the ridge never fully engulfs the region. There is a fairly pronounced trough in the eastern CONUS that is preventing the ridge from moving east once it reaches the high plains. There is also a closed low over Texas that also helps with inhibiting the eastward movement of the ridge.
519 PM EDT MON MAY 30 2016 Water vapor imagery continues to indicate an upper level trough across the Florida peninsula and adjacent waters and extends south of Cuba. the short term guidance is very similar to yesterdays in that it suggests that the persistent upper level trough could induce a weak low level trough early Tuesday morning.

Upper level ridging looks to be stronger again on Tuesday as short wave exits the region. By mid week, northern stream trough will deepen some and help push an upper level low to the east and begin to weaken upper level ridge.
340 PM CDT MON MAY 30 2016 (Tonight and Tuesday) An upper level low is centered across Arizona, putting West Central Texas in southwest flow aloft.
A cold front will then approach the region late week and stall over or near the area. High temperatures generally in the lower 80s north/ with mid to upper 80s south, warmest near the Altamaha River where it could reach 90. Through the day, models indicate that the low will make very little northeast progress, mainly just meandering in the general vicinity.
The exiting low pressure system has moved eastward faster that previously depicted, which has granted much of north central Idaho and western Montana a fairly pleasant Memorial Day.

SPC mesoanalysis currently showing a band of 1000+ J/kg MU CAPE along and south of the Highway 2 corridor, with the most recent update extending east of Grand Forks to near the western edge of Red Lake county. This is also on the nose of theta e ridge extending up from the south. The primary threats will be one inch or higher hail and winds of 58 knots or greater, and an isolated funnel is certainly possible along the warm frontal boundary to the south of Highway 2.
Another hot day is expected as an upper level ridge will continue to stretch from the western Gulf of Mexico through AL and the northwest FL Panhandle. Temperatures at 10 AM had already warmed into the upper 80s to around 90 across much of the region, and highs look on track to reach the lower to mid 90s inland, and around 90 near the beaches.

For tonight, a strong upper level trough will lift northeastward from far eastern Colorado and into Nebraska tonight. Strong west to southwest winds are still possible later this afternoon just behind the low west and south of Dodge City, then shifting to the northwest and increasing to 25 to 35 mph with higher gusts possible. The cold front looks to move across the Dodge City area by around 9 pm to midnight. Overnight lows will be around 28 to 32, except warmer around 35 to 40 for parts of south central Kansas. For Friday, the upper low will be moving away from the Central Plains and into the Upper Midwest.
Expect local freezing conditions Friday morning mainly east of Tucson.
As an upper level ridge builds in from the west expect gradually moderating temperatures through the weekend. Maliawco As the first winter storm of the central Rockies brings measurable snow to areas well to our south today, an area of relative high pressure keeps the snow away from northeast Montana. As the next upper-level ridge slowly moves west through the western states the flow over NE Montana will transition from NW late tonight to more zonal late tomorrow night.
High pressure along the eastern seaboard will move little tonight, then become oriented a little more southwest to northeast on Fri. The exception will again be the immediate coast, especially south of the Cape where a light northerly wind allows lows to stay in the lower or mid 60s. Ridging aloft over the eastern seaboard will maintain a strong subsidence inversion so return moisture will be meager and shallow. Will open up a wider range in min temps along the coast and bump up overnight clouds a little along the lower Treasure Coast, otherwise no changes planned. High pressure ridge to the north will provide a slowly veering wind from northeast to east.
Areas of frost with localized freezing temperatures is even forecast for the High Desert. Highs will be slightly above normal this weekend under weak high pressure aloft.
High pressure will return to the area tonight and build over the weekend.
On Friday, a cold front will approach South Texas with winds shifting to the north during the afternoon.
High pressure will build into the region tonight and Friday and will help to stabilize the atmosphere and with light winds there will be a chance for fog/stratus formation.

619 PM EST Thu Nov 17 2016 High pressure will prevail through late week.
603 PM EST Thu Nov 17 2016 Dry high pressure will extend into the area from the west through Friday with above normal temps.
Offshore flow at the surface plus a building ridge of high pressure lead to temperatures warming from the chilly values this morning. However, guidance indicates warming through the column translating to lows 3 to 5 degrees warmer. The ridge axis will move overhead on Friday and will combine with increasing southerly winds as a cold front nears our region.
Intense cold front will race through SW KS over the next 3 hours, with NW winds gusting 40-50 mph at times. Low stratus will rotate in overnight behind the departing cyclone. For tonight, a strong upper level trough will lift northeastward from far eastern Colorado and into Nebraska tonight. Strong west to southwest winds are still possible later this afternoon just behind the low west and south of Dodge City, then shifting to the northwest and increasing to 25 to 35 mph with higher gusts possible. The cold front looks to move across the Dodge City area by around 9 pm to midnight. Overnight lows will be around 28 to 32, except warmer around 35 to 40 for parts of south central Kansas. For Friday, the upper low will be moving away from the Central Plains and into the Upper Midwest.
Cold air advection will continue Friday night, pushing temperatures below freezing CWA-wide and likely providing the first real hard freeze for many areas since the advection cooling will be much more persistent than the brief, varying radiational cooling of the last "freeze.
The low in Iowa will weaken through this evening as the secondary low becomes the dominant weather feature. As this low track across Kansas and into western Iowa by 12Z Friday, upper level forcing will bring widespread accumulating snow into this CWA. A few lightning strikes have been observed with the upper level low in Colorado.
410 PM MST Thu Nov 17 2016 Upper low progressing east across central Colorado this afternoon with snow expanding slowly across the CWA. Friday will be cool with clearing skies across the CWA as high pressure slides across the area into the central and southern plains.
