NWS National Hurricane Center Miami FL
500 AM PDT Thu Jun 16 2022

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

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Blas, located a few hundred miles southwest of the southwest coast
of Mexico.

Off the coast of Central America:
Shower and thunderstorm activity has increased some with an area of
low pressure located a couple of hundred miles south of the coasts
of Guatemala and El Salvador. Environmental conditions are forecast
to become a bit more favorable over the next day or two and a
tropical depression is likely to form over the next couple of days.
This system is forecast to drift erratically through the weekend but
begin a more pronounced westward motion by early next week.
Regardless of development, locally heavy rains are possible across
portions of El Salvador, Guatemala, and southeastern Mexico during
the next several days.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...80 percent.

Issued at 1000 AM CDT Wed Jun 15 2022 305 WTPZ42 KNHC 151457 TCDEP2 Hurricane Blas Discussion Number 6 NWS National Hurricane Center Miami FL EP022022 1000 AM CDT Wed Jun 15 2022 Since the prior advisory, the structure of Blas has continued to improve on both conventional and microwave satellite imagery. In fact, several SSMIS microwave passes indicate that Blas is developing an inner core, with at least a banding mid-level eye feature showing up on the 89-GHz channel. The latest 1200 UTC subjective Dvorak estimates were T3.5/55 kt from TAFB and T4.0/65 kt from SAB. In addition, the most recent objective Dvorak estimates from UW-CIMSS have been quickly increasing with the latest estimate at T4.3/72 kt. A blend of the aforementioned data yields 65 kt for the advisory initial intensity, making Blas a hurricane. The center of Blas may have relocated a bit further south into the large overnight convective burst, but its mean motion this morning has continued a pronounced left turn, estimated at 290/4 kt. A continued west-northwest motion with some acceleration is anticipated over the next several days as the mid-level ridge poleward of the storm continues to build in and extend westward ahead of Blas. Towards the end of the forecast, Blas is expected to become a shallow system, resulting in a slowing westward motion as the low-level flow exerts greater influence. The latest forecast track has been adjusted a bit south in the short-term based on the adjusted initial position , but ends up just north of the previous forecast by the end of the period, close to the center of the track guidance envelope. The most recent microwave images suggest that Blas is developing an inner core, which would likely support further intensification today as the system remains over warm (28-29 C) sea surface temperatures (SSTs) embedded in sufficently high mid-level moisture. A possible complicating factor is that both the GFS- and ECMWF-based SHIPS guidance indicates easterly shear increasing to 20-25 kt over the next 24-36 h. Assuming this does not play a major inhibiting factor, the latest NHC forecast indicates continued intensification and peaks Blas as category 2 hurricane in 24 h. After 36 h, Blas will be crossing a sharp SST gradient, moving over sub 26 C waters by 60 h. For this reason, weakening is anticipated to begin by Friday. At the end of the forecast period, Blas is likely to lose its deep-convective activity and become a shallow low-level vortex. While Blas is expected to remain off the coast of Mexico, its associated swells are expected to affect portions of the coast of southwestern Mexico beginning today and continuing through the end of the week.

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0733 AM CDT Wed Jun 15 2022 Valid 151300Z - 161200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING OVER PARTS OF THE UPPER MIDWEST... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EARLY EVENING OVER PORTIONS OF THE SOUTHEAST STATES.... ...SUMMARY... Scattered severe thunderstorms are expected today across parts of the Upper Midwest into Upper Michigan. Several tornadoes, large to very large hail, and damaging winds all appear likely. Some of the tornadoes could be strong. ...Upper Midwest... Morning surface analysis shows a precipitation-reinforced boundary extending from central IA into WI. This boundary will move only slightly northward this afternoon as a strong shortwave trough currently over CO approaches. Increasing low-level winds and cyclogenesis along the boundary will lead to thunderstorm development by mid-afternoon from western WI into northeast IA. High and mid clouds will limit heating somewhat. However, dewpoints in the lower 70s and steep mid-level lapse rates will yield MLCAPE values of 3000+ J/kg. Strong deep-layer shear and large hodographs will promote supercells capable of very large hail and a few tornadoes (some strong) during the first several hours of the event. It is not clear how long activity will remain discrete before upscale organization occurs, with an increasing risk of damaging winds. Storms will move into Lower MI after dark, with a continued risk of locally damaging wind gusts. ...Southeast States... A hot and humid low-level air mass will be present today from the Carolinas southwestward into MS/AL, with widespread temperatures in the 90s and dewpoints in the upper 60s and lower 70s. This will result in MLCAPE values over 2000 J/kg and steep low-level lapse rates throughout the region. The details of the timing and location of convective development is uncertain this morning, but at least isolated thunderstorms are expected throughout the area. Sufficiently strong northeasterly flow aloft will aid in southwestward-propagating clusters capable of strong/damaging wind gusts. ..Hart/Mosier.. 06/15/2022 Read more

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Wed Jun 15 2022

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

The National Hurricane Center is issuing advisories on Tropical
Storm Blas, located a few hundred miles south of the southwest coast
of Mexico.

Off the coast of Central America:
A large area of showers and thunderstorms off the coast of Guatemala
and El Salvador are associated with a trough of low pressure.
Gradual development of this system is possible while it drifts
erratically, and it could become a tropical depression during the
next couple of days. Environmental conditions are forecast to
become less conducive for development by this weekend. Regardless of
development, locally heavy rains are possible across portions of El
Salvador, Guatemala, and southeastern Mexico during the next several
days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

As drought continues to drive the level of Lake Powell lower, the likelihood of invasive smallmouth bass crossing the Glen Canyon Dam increases, where the bass would be a threat to endangered fish in the Grand Canyon. Smallmouth bass prefer warm water and stay in the upper part of the water column, which is coming increasingly nearer to the intakes, which would transfer them to the river below. The problem with the bass becoming established below the dam is that the fish are thought to have decimated the humpback chub populations in the upper basin and would likely do the same with endangered fish below Glen Canyon Dam. Biologists are considering different ways of keeping the bass above the dam, but do not have any easy way of doing so. The Aspen Times (Colo.), June 13, 2022

Drought has led numerous growers in California to tear out orchards or vineyards because they do not have enough water or want to grow something else that needs less water. The cheapest way to get rid of the agricultural waste is to burn it, which many growers do rather than having the waste ground into mulch. The practice of burning agricultural waste has harmed air quality in the San Joaquin Valley, due to drought with more farmers burning and also due to the geography of the area that does not easily allow air pollution to escape. Los Angeles Times (Calif.), June 11, 2022

Drought prompted officials in Comal and Guadalupe counties to enact burn bans. New Braunfels Herald-Zeitung (Texas), June 13, 2022

MD 1164 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF EAST-CENTRAL GA INTO CENTRAL/SOUTHERN SC
Mesoscale Discussion 1164 NWS Storm Prediction Center Norman OK 1021 AM CDT Tue Jun 14 2022 Areas affected...portions of east-central GA into central/southern SC Concerning...Severe potential...Watch possible Valid 141521Z - 141615Z Probability of Watch Issuance...40 percent SUMMARY...Locally strong wind gusts are possible into early afternoon across portions of central/southern SC and eastern GA. DISCUSSION...Scattered thunderstorms are developing late this morning in a very moist and unstable environment in the vicinity of an outflow boundary from overnight convection. Regional 12z RAOBs and forecast soundings, in addition to recent mesoanalysis data, indicate some inhibition is still likely impacting the MCD area, but with continued heating this should erode over the next 1-2 hours. Surface dewpoints are generally in the 73-77 F range, supporting a corridor of strong MLCAPE with southward extent despite modest midlevel lapse rates. This strong instability will support initially robust thunderstorm updrafts. However, the region will remain under very weak vertical shear on the eastern periphery of the 500 mb ridge axis/upper anticyclone. This will ultimately limit longevity of intense updrafts and organized cells. However, if a strong enough cold pool can be generated, some forward propagation and organization of thunderstorm clusters could occur, with an attendant increase for locally damaging gusts. While a watch is not expected in the short-term, convective trends will be monitored. ..Leitman/Guyer.. 06/14/2022 ...Please see www.spc.noaa.gov for graphic product...
