Pumpkins seeds planted deeper near Morton, Illinois

2 years ago
A pumpkin grower near Morton, Illinois was afraid that the soil would be too dry to plant his pumpkin seeds since it had been 50 days since rain had fallen. He chose to plant the seeds deeper to hopefully help the seeds access moisture. Recent rainfall moistened the soil, helping the new plants push up through the soil. The dry spell may have shaved 30% off of his typical corn yield. High Plains Public Radio (Garden City, Kan.), July 17, 2023

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0136 PM CDT Tue Jul 18 2023 Valid 191200Z - 201200Z ...NO CRITICAL AREAS... The previous forecast remains valid with no changes. The threat for widespread fire-weather concerns is low. Please see the prior discussion. ..Lyons.. 07/18/2023 .PREV DISCUSSION... /ISSUED 0115 AM CDT Tue Jul 18 2023/ ...Synopsis... The upper-level ridge across the West will amplify and extend into more of the Canadian Rockies on Wednesday. At the surface, the pressure pattern will generally become more diffuse in the West. Mid-level moisture will remain underneath the ridge in the Great Basin and Southwest. With the weak surface winds expected, only locally elevated fire weather concerns are expected. This will primarily occur in the Southwest and southern Great Basin where fuels are dry. Mixed wet/dry thunderstorms are again expected in part of the Great Basin. The greatest coverage of storms will likely occur over central/northern Nevada and northern Utah. Storm motions may be similar to perhaps slightly slower than on Tuesday. PWAT values, though, will remain near an inch. The overall threat for ignitions still appears too low for highlights. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Tue Jul 18 2023 Valid 191200Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL PLAINS AND UPPER MIDWEST... ...SUMMARY... Scattered severe thunderstorms capable of producing large to very large hail and damaging winds appear possible Wednesday from the central Plains into the Upper Midwest. Isolated strong to severe thunderstorms may also occur from the Ozarks into the lower Ohio and Tennessee Valleys, along with the Carolinas and Mid-Atlantic. ...Synopsis... Upper ridging will remain confined to parts of the Northwest, Southwest, and southern Plains on Wednesday. A mid/upper-level trough/low is forecast to move from central Canada and the northern Plains across the Upper Midwest and Great Lakes through the period. A belt of enhanced (35-50+ kt) mid-level northwesterly flow should persist across these regions, and into parts of the mid MS and OH Valleys. A separate upper trough should progress over the eastern U.S. through the day. Multiple low-amplitude, convectively enhanced mid-level perturbations should advance generally east-southeastward within the west-northwesterly flow regime that will remain over much of the central/eastern CONUS. ...Northern/Central Plains into the Upper Midwest and Ozarks... As the upper trough/low moves east-southeastward, isolated to scattered thunderstorms will likely develop along and east/southeast of a cold front. Diurnal heating of a moist low-level airmass will foster the development of moderate to locally strong instability from parts of MN into southeastern SD, NE, and northwestern IA. Deep-layer shear of 40-50 kt will easily support supercells, with associated threat for both large hail and severe wind gusts. Isolated very large hail appears possible across parts of central/eastern NE and eastern MN/western WI with this activity. Based on consensus of latest guidance, have introduced a fairly broad Slight Risk to account for this supercell potential. The eastern extent of the severe risk should be modulated by the narrow zone of greater low-level moisture return. The southern extent of supercell potential into KS is rather uncertain, as large-scale ascent becomes increasingly modest into the central Plains. Still, there appears to be some risk for intense convection to develop/spread southeastward from NE into at least northern KS through Wednesday evening. Some potential also exists for a cluster of thunderstorms producing severe/damaging winds to spread from eastern CO into KS and perhaps eventually parts of MO Wednesday evening/night. ...Carolinas into the Mid-Atlantic... At least isolated thunderstorms may be ongoing Wednesday morning across parts of the Carolinas and Mid-Atlantic. Cloud cover and poor lapse rates may tend to limit the development of substantial instability until late Wednesday afternoon. Still, at least moderate instability should eventually develop and support robust updrafts. Better chances for strong to severe convection appear to exist along/east of a weak surface trough across eastern NC/VA/MD and vicinity. Occasional damaging winds should be the main threat with this activity, as deep-layer shear appears adequate for mainly multicells and small clusters. But, some hail may also occur with the strongest updrafts. Based on latest guidance, have expanded the Marginal Risk across this region to include more of eastern NC/SC and the Delmarva. ...Kentucky/Tennessee and Vicinity... Isolated to scattered thunderstorms may be present at the start of the period across this region. This activity may pose at least an isolated threat for severe hail and damaging winds, as deep-layer shear appears strong enough to support supercells. Most guidance shows a weakening trend to this morning convection. The potential for additional robust convective development in the wake of the morning thunderstorms is highly uncertain. But, some chance exists for renewed convection Wednesday afternoon/night along and south of a weak front. The environment will conditionally support a threat for all severe hazards, as enhanced northwesterly flow aloft appears sufficient for supercells. Have opted to include a fairly broad Marginal Risk across KY/TN and vicinity to account for potentially multiple rounds of strong to severe thunderstorms through the period. ..Gleason.. 07/18/2023 Read more

A watch is not expected given the localized/sporadic nature of the severe risk. DISCUSSION...Isolated thunderstorms are developing along the Mogollon Rim and far south-central AZ this afternoon, where temperatures have warmed into the 105-110 F range amid upper 50s dewpoints. The resulting deep boundary layer/steep low-level lapse rates -- characterized by an inverted-V thermodynamic profile -- will support dry microburts with severe-outflow potential with any stronger updrafts that develop. Weak deep-layer shear should generally limit updraft longevity/organization, and the overall coverage of severe storms is expected to remain too minimal for a watch. ..Weinman/Bunting.. 07/17/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0305 PM CDT Mon Jul 17 2023 Valid 172000Z - 181200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CENTRAL/SOUTHERN HIGH PLAINS TO THE OHIO VALLEY AND FROM EASTERN WYOMING SOUTHEAST INTO SOUTHWEST SOUTH DAKOTA AND NORTHERN NEBRASKA... ...SUMMARY... Severe storms producing large hail and damaging wind gusts are mainly expected from the Black Hills southeastward into Nebraska tonight, and across portions of the Ozarks and Lower Ohio Valley today. Shifted the slight/marginal risk farther north across the Ohio Valley to account for current location of the cold front and the threat for additional strong to severe thunderstorms. See MCD 1598 and 1599 for additional information. Expanded the marginal risk farther north into central Arizona. Thunderstorms are developing along the Gila Range with enough convective coverage for a potential cluster/cold pool to develop. The HRRR has trended toward this solution with the potential for some stronger wind gusts in a westward moving cluster this evening. Final change was expansion of the significant hail area across Missouri, into far western Illinois, and more of Kansas. The 18Z KSGF RAOB supports the potential for significant hail with nearly 4000 J/kg MLCAPE and 40 knots of effective shear. Storm mode will be the primary question as recent radar trends show significant upscale growth across central Missouri. This could mitigate the significant hail threat in that region and increase the potential for a concentrated severe wind swath. However, confidence is low how this cluster may evolve. Elsewhere, no changes were necessary. See MCD 1597 for information about northeast Oklahoma. ..Bentley.. 07/17/2023 .PREV DISCUSSION... /ISSUED 1153 AM CDT Mon Jul 17 2023/ ...Central/southern Plains east Ozarks and Ohio Valley... Moderately strong northwest/west mid-level flow will persist from the central/southern Plains east to the OH Valley through tonight. Heating of a moist air mass ahead of a nearly stationary front, combined with a plume of steep mid-level lapse rates will result in a rather large region of strong to locally extreme instability in the presence of substantial deep-layer shear supportive of organized storms. Ongoing severe storm cluster over southeast KS will likely continue moving south-southeast into an environment characterized by 40-50 kts of shear and MLCAPE of 3000-4000 J/jg. Damaging winds and potentially very large hail will be possible with this complex as it moves across northeast OK. Additional thunderstorm development is likely across the Ozarks vicinity along remnant outflow boundaries this afternoon, ultimately resulting in additional clusters or line segments moving southeast/south through this evening. Damaging winds will be the primary severe threat, and with large (isolated very large) hail with the more discrete/intense updrafts. Across the OH Valley, clusters of thunderstorms are expected to develop as clearing/heating occurs in the wake of morning storms. Effective shear of 30-40 kts will support both supercell and multicell clusters persisting through the late afternoon and early evening with severe wind/hail potential. ...Eastern Wyoming/Black Hills/Nebraska... A sharpening lee trough ahead of the northern Rockies upper trough will result in moist low-level upslope flow into the Black Hills/eastern Wyoming and southeast Montana vicinity. The proximity of the upper ridge may somewhat temper the extent of deeper convection, however at least isolated thunderstorms are expected to develop by late afternoon/early evening in a moderately unstable and strongly sheared environment, with storms increasing in coverage toward/after sunset. Steep lapse rates and long straight hodographs will support large to locally very large (greater than 2 inch diameter) hail. As the low-level jet strengthens during the evening, upscale development into a bowing MCS is possible as convection tracks southeastward across western/southern South Dakota and Nebraska. Damaging gusts, potentially significant, may accompany this MCS during the evening and overnight hours, and a Significant Wind area has been added with this outlook. ...Northern Great Basin and Central/Eastern Montana... Moderate to strong west-southwest mid/upper-level flow will overspread the region ahead of the northern Rockies upper trough. Steep mid-level lapse rates and moistening will support MLCAPE around 500-1250 J/kg. Well-mixed boundary layers will result in mostly high-based, low-precipitation convection capable of sporadic strong dry microburst winds from far northeast Nevada/northern Utah into central Montana. With eastward extent into parts of eastern Montana, deeper boundary-layer moisture will result in the potential for isolated strong gusts as well as hail. ...Southern AZ... Diurnal heating of a moist environment (PW 1.5 inches) will contribute to afternoon MLCAPE of 1000-1500 J/kg. Thunderstorm development is expected this afternoon, and dry mid-levels with 15-20 kts of easterly flow will result in a risk for gusty/damaging winds as storms move west through evening. Read more
