NO FLOOD THREAT IS FORECAST.<\/em><\/p>\n

The same general upper-air pattern remains across the continental US, generally characterized by a high pressure ridge across the central US, flanked by a trough<\/span> on either coast. The upper-level high pressure is expected to stay centered over Texas today; this is a bit further east than yesterday, thanks to the upper-level low pushing onshore over the Pacific Northwest. This will force drier air into the state today as flow becomes more westerly, but decent mid-level moisture will hang to the south and east of a line bisecting the state from southwest to northeast.<\/p>\n

For High Country areas underneath the drier air, i.e., the Northwest Slope, Northern Mountains, Grand Valley, and Southwest Slope, sunny skies and hot temperatures will be the main story today, with fair weather clouds breaking up the sunshine. A bit better moisture will hang out over the Central Mountains and Front Range, so a couple isolated<\/span> showers\/weak thunderstorms cannot be ruled out, especially across southern portions.<\/p>\n

Isolated<\/span>-to-scattered<\/span> coverage of thunderstorms is expected over the higher terrain of other western Colorado regions (San Juan Mountains, San Luis Valley, and Southeast Mountains). With precipitable water<\/span> values running below average for this time of year, rain rates will not be particularly impressive, and the biggest impacts will be gusty outflow<\/span> winds and dangerous lightning.<\/p>\n

For eastern Colorado, mostly sunny skies and hot temperatures will be the name of the game for most. Near the interface with the higher terrain, a few isolated<\/span> showers\/weak thunderstorms will move overhead off the mountains for southern portions of the Urban Corridor and western portions of the Southeast Plains. The best chance for thunderstorms today will be along the CO\/NM and CO\/KS borders, where a surface boundaries will enhance thunderstorm development a bit. With relatively dry air still in place below cloud bases, the main threats will be strong winds and large hail. Brief moderate rainfall will attend the strongest storms near the CO\/KS border across the Southeast Plains and southeastern portions of the Northeast Plains, but dry air and storm motions will limit the impacts to minor street\/field ponding.<\/p>\n
