Surface weather map

A flat rectangular synoptic surface weather map in clean textbook meteorological chart style on a pale white or light background, with simplified outlines of North America emphasizing the United States and southern Canada or nearby coastlines. Numerous smooth thin black isobars curve and loop around pressure centers and are labeled with values such as 996, 1000, and 1004. Prominent pressure-center markers include a blue H for high pressure and a red L for low pressure. Standard frontal boundaries are shown with analytical lines, including blue triangles for cold fronts, red semicircles for warm fronts, and optionally purple occluded segments. Small station plots or station-model symbols are scattered across the map, some with compact weather markings, wind barbs, or pressure labels. No terrain shading; overall appearance is minimal, analytical, and professional.
