information from the surface to FL240 (400 mbs), Altitudes from the surface to 17,999 are referenced using MSL altitudes, Altitudes from 18,000' to FL240 are referenced using pressure altitude, Provided in two forecasts, 12 and 24 hours in 4 panels, Two top panels depict the 12 and 24 hour produced at the Aviation Weather Center (AWC) in Kansas City, Missouri, Two lower panels depict the 12 and 24 hour produced at the Hydro meteorological Prediction Center (HPC) in Camp Springs, Maryland, HLSWPC is a day 1 forecast of significant weather in the conterminous United States, Provides information from 24,000' to 60,000', Covers much of the Northern Hemisphere and a limited portion of the Southern Hemisphere, Each section covers a specific area and areas sometimes overlap, Conditions routinely appearing on the chart are jet streams, cumulonimbus clouds, turbulence, and Tropopause heights, Surface fronts are included to add perspective, Sometimes tropical cyclones, squall lines, volcanic eruption sites, sandstorms, and dust storms will appear, Depict pressure centers, troughs and on selected panels, isobars, High and Lows identified by "Hs" and "Ls" respectively, Pressure troughs are identified by long dashed lines labeled "TROF", Isobars are drawn as solid lines to portray pressure patterns, Isobars are drawn in 8 millibar (mb) intervals instead of 4 mb to provide a less sensitive analysis, Occasionally, nonstandard isobars will be drawn using 4 mb intervals to highlight patterns with weak pressure gradients, Nonstandard isobars are drawn as dashed lines, Surface fronts are depicted on each panel, Formats used are the standard symbols and three-digit characterization code used on the surface chart, Symbols specify the forums and types of precipitation, A mix is indicated by the use of two pertinent symbols separated by a slash, Areas of continuous precipitation is shaded as well as precipitation covering more than half of the area, A bold dashed line is used to separate precipitation with contrasting characteristics, A dashed line would be used to separate an area of similar characteristics (snow and rain), Jet streams with a maximum speed of more than 80 knots are identified by bold lines, Arrowheads indicate the orientation of each jet stream, Double hatched lines identified changes in wind speed, Speed indicators are drawn at 20-knot intervals and begin with 100 knots, Standard wind symbol (shaft, pennants, and barbs) is placed at each pertinent position to identify velocity, The altitude in hundreds of feet prefaced with "FL" is placed adjacent to each wind symbol, Cumulonimbus clouds (CBs) are thunderstorm clouds, Isolated or scattered CBs (one-half or less coverage) which are not embedded are not depicted, Bases that extended below 24,000 are encoded "XXX" (High-Level), Thunderstorms imply hazards including turbulence and hail, Centers of high and low heights are identified with "H" and "L" respectively with their heights and enclosed by polygons, Ceiling and visibility determine the category, MVFR areas are enclosed by scalloped lines, Depicted by a zigzag line labeled as "SFC" for surface, Freezing levels aloft are depicted by thin, short dashed lines, Lines are drawn at 4,000' intervals (80 = 8,000'), Lines are discontinued where they intersect corresponding altitudes of the Rocky Mountains, Areas with multiple freezing levels have lines drawn to the highest freezing level, Areas of moderate or greater turbulence are enclosed by bold, long dashed lines, Turbulence intensities are identified by symbols, The vertical extent of turbulence layers are specified by top and base heights, Areas of thunderstorms do not include indications of turbulence because it is implied, Added emphasis is included if the turbulence is from the surface to 24,000' or above, having thunderstorms covering more than half of the area, Intensity symbols and layer altitudes appear within or adjacent to the forecast area, Positions of hurricanes, typhoons and tropical storms are depicted, Hurricanes use standard symbol while typhoons are shaded, When pertinent the name of each storm is positioned adjacent to the symbol, Severe squall lines are lines of CBs with 5/8 coverage or greater, Identified by long dashed lines separated by a V, Dot at the base indicates latitude and longitude of volcano, Name, latitude, and longitude are noted adjacent, Areas of widespread sandstorms and dust storms are labeled by an S, The S with an arrow depicts areas of widespread sandstorms or dust storms, The S without an arrow depicts severe sandstorm or dust haze.
