MD 1842 CONCERNING SEVERE THUNDERSTORM WATCH 613... FOR EASTERN COLORADO...FAR WESTERN KANSAS...PORTIONS OF TEXAS/OKLAHOMA PANHANDLES...FAR NORTHEAST NEW MEXICO.
Mesoscale Discussion 1842 NWS Storm Prediction Center Norman OK 0528 PM CDT Fri Aug 23 2019 Areas affected...Eastern Colorado...far western Kansas...Portions of Texas/Oklahoma Panhandles...far northeast New Mexico. Concerning...Severe Thunderstorm Watch 613... Valid 232228Z - 240030Z The severe weather threat for Severe Thunderstorm Watch 613 continues. SUMMARY...The severe weather threat continues for WW 613. Severe wind gusts and large hail will be the primary threats from two storm clusters in eastern Colorado and portions of the TX/OK Panhandles. Some possibility for a tornado exists with storms interacting with an outflow boundary in western Kansas. DISCUSSION...Current radar mosaic shows two primary clusters of storms within WW 613. One cluster east of Denver has had a history of relatively discrete storms producing large hail, with one report of 1.75 inches. Storms in the southern portions of the Watch have congealed into more of a linear structure in the Panhandles. Deep boundary layer mixing has led to dewpoints in the low to mid 50s F across most of eastern Colorado into the TX/OK Panhandles. Combined with modest low-level shear, the expectation is for these two clusters to continue to grow upscale this evening and propagate east/southeastward. Visible satellite imagery has shown agitated cumulus increasing along an outflow boundary from near Dodge City, KS into northeastern Colorado. Near this boundary, both deep-layer (around 40 kts effective) shear and low-level shear will be maximized. The KDDC VWP shows around 100 m2/s2 0-1 km SRH. Storms that can form along/interact with this boundary will have some potential to produce a tornado before likely moving into more stable air across the boundary. ..Wendt.. 08/23/2019 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1843 NWS Storm Prediction Center Norman OK 0632 PM CDT Fri Aug 23 2019 Areas affected...NE Panhandle Concerning...Severe Thunderstorm Watch 614... Valid 232332Z - 240030Z The severe weather threat for Severe Thunderstorm Watch 614 continues. SUMMARY...The potential for severe gusts (60-70mph) is increasing as storms grow upscale into a squall line near the WY/NE border and move east into the NE Panhandle this evening. DISCUSSION...Radar mosaic shows an intensifying band of storms over far southeastern WY. RAP forecast soundings show 700-500mb lapse rates approaching 9 degrees C/km atop a moisture-rich boundary layer with low-middle 60s surface dewpoints in the NE Panhandle. Despite the relatively weak flow in the troposphere, strong veering of the wind profile is at least resulting in deep-layer shear supportive for multicell organization in the form of a squall line. The primary hazard will be severe gusts in the 60-70mph range. ..Smith.. 08/23/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BOU...CYS...

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Fri Aug 23 2019

For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on Tropical
Storm Ivo, located a few hundred miles west-southwest of the
southern tip of the Baja California peninsula.

A surface trough located about 1000 miles east-southeast of the Big
Island of Hawaii is producing limited shower and thunderstorm
activity. Environmental conditions could become a little more
conducive for some development in a few days as the system moves
northwestward. Future information on this disturbance can be found
in Tropical Weather Outlooks issued by the Central Pacific Hurricane
Center.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.

An area of low pressure is forecast to form just offshore of the
west-central Mexico coast near the southern tip of the Baja
California peninsula by the middle of next week. Some development of
this system is possible thereafter while it moves westward or
west-northwestward at around 10 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.

These storms should grow upscale over the next couple hours or so, possibly requiring a WW issuance. DISCUSSION...Latest satellite imagery and objective analyses suggest a gradual increase in towering cumulus against higher terrain of central/south-central Colorado and adjacent areas of New Mexico within a weak upslope regime and easterly/southeasterly surface winds. Meanwhile, temperatures have risen into the upper 80s in most areas, which has increased surface-based CAPE values into the 2000-3000 J/kg range amidst steep low- and mid-level lapse rates. Observational trends and model guidance suggest that convection will continue to expand with time, and some upscale growth into linear segments is expected given weak low-level shear and maturing cold pools. Damaging wind gusts and large hail are expected to be the primary threats with this activity. Convective trends are being monitored, and a WW issuance may be needed around or before 21Z. ..Cook/Thompson.. 08/23/2019 ...Please see www.spc.noaa.gov for graphic product...

Castle Fire (Wildfire)

5 years 11 months ago
The Kaibab National Forest has been allowing the lightning-caused Castle Fire to spread within a defined area in order to fulfill its natural role of reducing dense forest fuels and improving overall ecosystem health. The wildfire has now moved across the entire 19,368-acre planning area, and additional perimeter growth is not anticipated. However, pockets of unburned vegetation remain within the wildfire's interior and may burn over the coming days. The Castle Fire has been burning in an area with dense mixed conifer, heavy fuel loading, and a significant amount of dead and down trees. Allowing the fire to act as a natural disturbance process in the ecosystem helps meet a variety of resource objectives including restoring the forest structure to more historic conditions, reducing spruce and fir encroachment of area meadows, removing fuels that could feed future severe wildfires, and promoting aspen regeneration. A temporary Closure Order is in place for the Castle Fire area,...

Tropical Storm Ivo Forecast Discussion Number 11

5 years 11 months ago
Issued at 200 PM PDT Fri Aug 23 2019 000 WTPZ45 KNHC 232039 TCDEP5 Tropical Storm Ivo Discussion Number 11 NWS National Hurricane Center Miami FL EP102019 200 PM PDT Fri Aug 23 2019 The satellite appearance of Ivo has changed little today, with northeasterly shear confining the deep convection to the southwestern semicircle of the cyclone's circulation. Although recent ASCAT data suggests that the peak winds may have decreased, the initial intensity is conservatively maintained at 55 kt, based on the earlier wind report from Clarion Island. Ivo's initial motion is 335/09 kt. This general motion is expected to continue for at least the next 48 hours as the cyclone is steered around the western periphery of a mid-level ridge over northern Mexico. Once the cyclone weakens and becomes a shallow system in a couple of days, the forward motion should decrease and a turn to the northeast should occur, as the circulation becomes steered by the low level flow. The official forecast track is very close to the previous one and is near the various consensus model solutions. Although guidance suggests the wind shear will decrease over Ivo starting in about 12 hours, the cyclone is beginning to move over progressively cooler waters. This should cause the cyclone to gradually weaken over the next couple of days. By Sunday afternoon, Ivo will be over SSTs of about 22 C and in a more stable airmass. This should cause the cyclone to become devoid of deep convection and degenerate into a remnant low around that time. The latest forecast is an update of the previous one and in agreement with the corrected consensus HCCA.
