MD 2056 CONCERNING SEVERE THUNDERSTORM WATCH 609... FOR CENTRAL HIGH PLAINS
Mesoscale Discussion 2056 NWS Storm Prediction Center Norman OK 0726 PM CDT Tue Sep 09 2025 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 609... Valid 100026Z - 100230Z The severe weather threat for Severe Thunderstorm Watch 609 continues. SUMMARY...Hail threat is expected to persist with storms this evening, along with some wind risk. DISCUSSION...Isolated strong-severe thunderstorms are shifting slowly southeast across the central High Plains this evening. Strong boundary-layer heating has proven instrumental in this activity attaining severe levels as lapse rates are seasonally steep across this region. However, over the next few hours, nocturnal cooling will lead to increasing CINH and surface-based updrafts should being to struggle as they decouple from the boundary layer. 00z sounding from DDC exhibits this trend with weak inhibition noted around 1km. Even so, LLJ is forecast to increase after sunset and this should aid one or more elevated thunderstorm clusters that should propagate across western KS. Hail is the primary concern with this activity. ..Darrow.. 09/10/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DDC...GLD...PUB...BOU...

DISCUSSION...A few storms have slowly intensified in northeast Colorado and the Nebraska Panhandle as they move east into greater low-level moisture. This is primarily in response to a weak shortwave trough moving through the upper-level ridge in the High Plains. Effective shear of 30-40 kts (stronger to the east) will support isolated, marginally organized convection. The overall lack of moisture and large-scale lift will limit storm intensity. Increasing MLCIN--evident on the 18Z observed LBF sounding--to the east should also keep the spatial extent of the stronger activity limited. The well-mixed boundary layer could promote isolated severe winds. Storms that can maintain a discrete mode could produce marginally severe hail as well. Overall, activity should begin to gradually diminish by sunset as CIN increases further. ..Wendt/Mosier.. 09/09/2025 ...Please see www.spc.noaa.gov for graphic product...

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Tue Sep 9 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Kiko, located in the central Pacific basin a couple of
hundred miles east-northeast of Oahu in the Hawaiian Islands.

South of Southern and Southwestern Mexico (EP95):
A tropical wave located a few hundred miles south of the Gulf of
Tehuantepec is producing a large area of disorganized showers and
thunderstorms. Environmental conditions are favorable for
development of this system, and a tropical depression is likely to
form by late this week as it moves west-northwestward, roughly
parallel to but offshore of the Mexican coast.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...80 percent.

WW 609 SEVERE TSTM CO KS 092050Z - 100300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 609 NWS Storm Prediction Center Norman OK 250 PM MDT Tue Sep 9 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado Western Kansas * Effective this Tuesday afternoon and evening from 250 PM until 900 PM MDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorms are expected to develop and intensify through the late afternoon and early evening across the watch area. Large hail will be the main concern, along with gusty winds in the strongest storms. The severe thunderstorm watch area is approximately along and 70 statute miles north and south of a line from 45 miles west southwest of Burlington CO to 30 miles north of Garden City KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 34015. ...Hart Read more

A "significant" drought was declared for the majority of Massachusetts, including central and western regions, the northeast part of the state, Cape Cod and Nantucket. Southeast portions of the state are experiencing mild drought. Rainfall has been below normal for the past three months. The public was urged to conserve water. Cities in significant drought were to immediately limit or prohibit vehicle and pavement washing. CBS Boston (Mass.), Sep 9, 2025

MD 2054 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FAR EASTERN NM INTO PARTS OF THE TX PANHANDLE/SOUTH PLAINS
Mesoscale Discussion 2054 NWS Storm Prediction Center Norman OK 0337 PM CDT Tue Sep 09 2025 Areas affected...Far eastern NM into parts of the TX Panhandle/South Plains Concerning...Severe potential...Watch unlikely Valid 092037Z - 092230Z Probability of Watch Issuance...20 percent SUMMARY...Strong to locally severe storms are possible late this afternoon into the evening. DISCUSSION...Storm initiation is underway across Roosevelt County, NM as of 2030 UTC, with increasing cumulus noted farther north. In addition to the ongoing development, continued strong heating and weakening of MLCINH may eventually result in isolated storm development farther east into parts of the TX Panhandle/South Plains, near a weak surface confluence zone. Initial high-based convection closer to the NM/TX border would pose a threat of localized strong to severe gusts within the deeply mixed environment. While deep-layer shear is relatively modest, isolated hail cannot be ruled out given the presence of steep midlevel lapse rates and MLCAPE of around 1000-1500 J/kg. Any storms that develop or move farther east could pose a somewhat greater hail threat, given the presence of richer low-level moisture and greater MLCAPE. Coverage of the severe threat is expected to remain rather isolated, rendering the need for a watch uncertain in this area. However, within the northwesterly flow regime, only a slight increase in deep-layer shear compared to what is currently observed/analyzed could support potential for a supercell or two, and observational trends will continue to be monitored regarding the need for watch issuance. ..Dean/Hart.. 09/09/2025 ...Please see www.spc.noaa.gov for graphic product...

Hay fed to cattle, lower hay production in Hartford, Vermont

2 weeks 4 days ago
A livestock producer in Hartford, Windsor County, Vermont has 15 angus cows and is trying to expand the herd. Hay production has amounted to just 162 round bales, in comparison to the 300 round bales that he typically gets. He abandoned a second cutting of hay and let the livestock graze fields. The surplus hay would normally be sold, but this year he won’t have much to spare and anticipated having to put out silage for the cows about a month and a half early.

Hay fed to cattle in Lyme, New Hampshire

2 weeks 4 days ago
Steams were running dry, trees were shedding their leaves early, burn bans were in effect, and farmers were working to care for their livestock. In Lyme, New Hampshire, cattle were consuming the first cutting of hay as the pastures were reduced to crunchy grass. The cattle would not normally get hay until much later in fall, and the farmer was hoping to get one more hay cutting. During an average year, enough hay is harvested to keep the cattle fed through winter without buying any hay, but this year, the hay purchases have already begun with three round bales at $75 each.
