![]() The late-week rainfall helped to stave off further degradation of drought in upstate areas of the Carolinas and Virginia however, another round of deterioration was warranted across the Coastal Plain of North Carolina and the Virginia Tidewater, as short-term precipitation and soil moisture deficits continue to increase and average stream flows continue to decline. In the days leading up the the end of the week (Tuesday, 6/20), an area of low pressure developed across the Middle Mississippi Valley and began slowly moving eastward, leading to periods of additional rainfall across some of these same areas, in addition to interior and upstate portions of the Carolinas and Virginia. Many areas received more than 5 inches of rainfall as these thunderstorm clusters moved southeastward along a mean frontal boundary. Several rounds of heavy rainfall associated with clusters of thunderstorms warranted improvement to abnormal dryness (D0) and moderate drought (D1) across southern portions of the Deep South from Mississippi to Georgia and into northern Florida. Unfortunately, short-term dryness leading up to this week warranted further degradation of drought and abnormal dryness (D0) across southern New England and the Mid-Atlantic from the I-95 corridor eastward to the Atlantic Coast. Some locations in southeastern Pennsylvania and northern West Virginia also experienced improving drought conditions, associated with a couple of rounds of heavy rainfall, totaling in excess of 2 inches for the week. Several locations in interior portions of the Northeast also received well above normal rainfall totals, leading to improvements in the drought depiction, particularly across northern New England and parts of Upstate New York. Much of the Northeast experienced below average daytime high temperatures this week. Another round of deterioration was warranted again this week across much of the Midwest and eastern Great Plains, where below average precipitation continued to add to precipitation deficits that go back several months. However, much of the Mississippi and Ohio Valleys and the Northeast experienced a mix of worsening and improving drought conditions based on antecedent dryness and where the heaviest rain fell, respectively. Toward the end of the weekend, a slow-moving storm system traversing eastward across the Middle Mississippi and Ohio Valleys resulted in additional periods of heavy rainfall across portions of the eastern U.S. Heavy rain also fell across parts of the Southeast, with many locations across the Deep South receiving in excess of 5 inches of rainfall, leading to improvements to abnormally dry and moderate drought conditions from central Mississippi southeastward to Florida. The only exception was in the northern Cascades in Washington, where below-normal precipitation led to worsening drought conditions. A mean frontal boundary draped across much of the lower 48 states resulted in periods of heavy rainfall across portions of the western Great Plains and Intermountain West, leading to improvements to drought conditions across much of the western half of the lower 48 states. Large portions of southern Texas experienced excessive heat this week, with daytime high temperatures averaging well above 100☏ for several locations. The application speed depends on the type of application and goes up to 6 km/h.Much of the lower 48 states experienced near to below normal temperatures this week, with the exception of parts of the northern Great Plains, Upper Midwest, southern Texas, and parts of the Lower Mississippi Valley. This avoids settling and catching of solid parts and prevents unnecessary wear of mechanical parts. Continuous circulation of the thermoplastic material inside the equipment. It can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of the layer. ![]() Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven. The shutters have no contact with the high tensile steel drum and therefore wear is minimalized and lifetime is prolonged. The number of dots/meter is 15-35 dots and is controlled by the LineMaster. The diameter of dots can be chosen between ø18 and ø 45 mm depending on the chosen drum. Consequently, the Dots will settle on top of the line with sharp edges, securing the optimum retroreflection. By using two sets of shutters the base line has time to cure slightly before the Dots are applied. ![]()
