Today's Weather Story

Hot temperatures have returned to northern California. Daytime highs today and Thursday are likely to hit record highs for the date in some locations. If in the heat over the next few days, remember to follow the heat safety rules.

Summer Season Weather Safety Website

Heat is here, but you can get prepared and #BeatTheHeat. On the map, check to see if you’re in a red area. If you are, here’s what you need to know. Heat-related impacts are likely if precautions are not taken. Heat events like this happen only a few times a year, and some people in the area won’t have had previous experience with dangerous heat like this. Sensitive groups (e.g. elderly and very young) will need assistance to avoid heat-related illness and should be helped to prepare and checked on frequently. And as always, never, ever leave a child or pet in an enclosed automobile.

Hot weather for interior of northern California this week! Be prepared! Mountain thunderstorms Friday through Monday will bring a threat of new fire starts.

Severe storms possible in Midwest

Isolated Severe Thunderstorms Will Continue

Isolated severe thunderstorms will continue from Minnesota to southwestern Kansas and vicinity. Within that swath, the most probable area for greater concentrations of severe weather is from eastern Nebraska across parts of Iowa. A marginal risk for severe thunderstorms also exists over eastern New England.

...Hot and humid weather to continue over areas of the southern U.S.

...Flash flooding possible over areas of New Mexico and the Texas/Oklahoma panhandles through Thursday morning...

...Above normal temperatures to prevail across the western U.S...

The upper pattern across the country will feature a broad ridge extending from the Southern Plains toward the Deep South. To the north, a high amplitude and progressive jet structure will help carve a trough over eastern Canada toward the end of the week. Meanwhile, ridging will begin to extend over a vast majority of the western states supporting above normal temperatures.

Underneath the aforementioned ridge across the southern sector of the U.S., hot and humid conditions will continue. Local forecast offices have placed an expansive region from eastern Oklahoma across the Lower Mississippi valley and into the Mid/Deep South in heat advisories and excessive heat warnings. Expect heat indices to locally exceed 105 degrees in some of the previously mentioned areas.

To the west of this ridge, a series of mid-level disturbances will track through the Desert Southwest and Four Corners region. These features combined with sufficient moisture and diurnal heating will support a broad area of convection. In particular, a more focused area of thunderstorms moving through northeastern New Mexico this evening may cause rainfall heavy enough to produce flash flooding. This threat will gradually shift eastward toward the Texas/Oklahoma panhandles into the overnight hours.

The other region of active weather will be along and ahead of a rather pronounced cold front currently sweeping through the Upper Great Lakes. While the boundary should weaken in time as the better upper support lifts into Canada, expect showers and thunderstorms to accompany frontal passage. It appears this will occur by around Thursday evening along the I-95 corridor. Overall, the heaviest rainfall looks to be along the eastern Gulf Coast where a mid-level impulse is expected to sink southward from the Lower Tennessee valley toward the Gulf Coast. WPC is currently highlighting a broad area of 1 to 2 inches of precipitation over this area through Friday morning.

Elsewhere, a building ridge along the West Coast will maintain hot conditions through at least Friday. Temperature anomalies of 10 to 15 degrees above normal will support highs reaching the century mark. In fact, temperatures should hit the 105 to 110 degree range over the interior valley locales of California and Oregon on Thursday.

NOTE: The HPC National Forecast Map above, provides an overview of today’s national weather with an emphasis on certain hazardous and significant weather. It summarizes forecasts from several NCEP Service Centers including the Storm Prediction Center (for severe thunderstorm and tornado outlooks), the National Hurricane Center (for tropical storm and hurricane forecasts), and the Hydrometeorological Prediction Center (for information concerning heavy rainfall, flooding, winter weather, and general weather). With an overlaid frontal forecast, this display serves as a great overview of the weather for the current day! The National Forecast Map is prepared twice daily at the Hydrometeorological Prediction Center.
