Fire emergency in North Dakota

5 months 1 week ago
North Dakota Gov. Armstrong declared a statewide fire emergency and activated the State Emergency Operations Plans as warmer than normal temperatures and below normal precipitation has led to drought and increased the fire risk. The declaration has all state agencies like the North Dakota Department of Emergency Services, North Dakota Forest Service and North Dakota National Guard on standby. The order expires on May 31.

Conditions worsened for Connecticut River Valley in Massachusetts

5 months 1 week ago
The Connecticut River Valley region was categorized as being in a Level 3 Critical Drought, a move from Level 2 Significant Drought. The state has dealt with nearly seven months of below normal precipitation. Massachusetts residents were urged to conserve water as much of the state remained in critical or significant drought after almost seven months of below normal precipitation.

SPC Day 3-8 Fire Weather Outlook

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0416 PM CDT Mon Mar 10 2025 Valid 121200Z - 181200Z An extended period of critical fire-weather conditions is expected across much of the southern Plains through the extended forecast period. The day of greatest concern is Day 5/Friday, when high-end critical to extremely critical conditions appear likely. ...Days 3-4/Wednesday-Thursday - Southern Plains... A robust low-latitude shortwave trough and strong midlevel westerly flow will cross the southern Rockies and adjacent Plains on Day 3/Wednesday. Deep boundary-layer mixing behind an associated dryline and a tightening surface pressure gradient will favor critical fire-weather conditions across the southern Plains. Thereafter, a highly amplified large-scale trough will track eastward across the West, resulting in a deepening lee trough and dry/windy conditions across the southern High Plains on Day 4/Thursday -- where critical conditions are expected. The 70-percent Critical probabilities for Day 4/Thursday may need to be expanded northward into the central High Plains if guidance comes into better agreement with the overlap of strong surface winds and low RH. ...Day 5/Friday - Southern Plains... In the base of the highly amplified large-scale trough, a 100+ kt west-southwesterly midlevel jet will overspread the southern and central Plains, while a related surface cyclone rapidly deepens over the central High Plains. South of the surface cyclone and west of a related dryline, 30+ mph sustained westerly surface winds (with gusts upwards of 60-70 mph) will overlap single-digit to lower teens RH across portions of the southern Plains. Given increasingly dry/receptive fuels, high-end critical to extremely critical conditions can be expected. ...Days 6-8/Saturday-Monday - Southern Plains... On the backside of the amplified midlevel trough, a reinforcing midlevel jet streak will impinge on the southern Plains, favoring another day of critical conditions on Day 6/Saturday. Substantial differences among the medium-range guidance limits forecast confidence thereafter, though the overall pattern should support continued fire-weather concerns on Days 7-8/Sunday-Monday, with critical conditions possible both days (especially Day 8/Monday). ..Weinman.. 03/10/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1145 AM CDT Mon Mar 10 2025 Valid 101700Z - 111200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NORTHERN PLAINS... The previous forecast (see below) remains on track, and no changes were made with this update. In addition, dry/breezy conditions along the CO Front Range may favor locally elevated fire-weather conditions (especially in the gap flow areas) today. However, these conditions and receptive fuels appear too localized for highlights. ..Weinman.. 03/10/2025 .PREV DISCUSSION... /ISSUED 0139 AM CDT Mon Mar 10 2025/ ...Synopsis... A mid-level impulse will traverse the north-central CONUS today, encouraging surface troughing across the northern Plains into the southern High Plains, with a surface cold front poised to surge southward across the northern Plains during the later half of the period. Preceding the surface cold front, within the surface troughing regime, dry and windy conditions are expected across portions of the northern and central Plains. Over the central Plains, 15-25 mph west-southwesterly sustained surface winds amid 15-20 percent RH will encourage Elevated wildfire-spread potential given dry fuels. Across the northern Plains, closer to the stronger upper support, sustained westerly surface winds may reach 20 mph in spots, with sustained northwesterly surface winds potentially exceeding 30 mph behind the cold front. Given dry fine fuels and RH dipping to at least the 15-25 percent range by afternoon peak heating, Elevated/Critical highlights have been maintained. ...Please see www.spc.noaa.gov/fire for graphic product...

The previous forecast remains on track, and no appreciable changes were made with this update. For details, see the previous discussion below. Farther east, a modest pre-frontal pressure gradient and ample diurnal heating/boundary-layer mixing will favor breezy/gusty southwesterly surface winds and around 30 percent RH from the Ohio Valley into the Mid-Atlantic and Northeast during the afternoon.

By afternoon peak heating, west-southwesterly surface winds in the 15-25 mph range will become common, along with RH dipping to 5-15 percent.
