Dry Conditions Prevail
High pressure will continue to allow for dry weather across the region.
General Overview: SIGNIFICANT PRECIPITATION EXPECTED ACROSS THE WEST WITH HEAVY RAIN AND FLASH FLOODING POSSIBLE IN CALIFORNIA. MIXED PRECIPITATION AND POTENTIAL FREEZING RAIN DEVELOPING IN THE NORTHEAST AND GREAT LAKES REGION BY SATURDAY. ABOVE NORMAL TEMPERATURES WILL DOMINATE THE CENTRAL US THROUGH THE PERIOD.
EAST: A relatively quiet weather pattern will prevail across the Eastern US through Friday, with high pressure systems dominating the Southeast and Mid-Atlantic regions. By Saturday, a developing low pressure system over the Great Lakes will bring rain to much of the Northeast and Mid-Atlantic. This system will intensify, with mixed precipitation developing across portions of New England, New York, and the Great Lakes. There is potential for freezing rain in parts of northern New England and eastern Great Lakes by Saturday evening, which could create hazardous travel conditions. Rain will spread southward along the Eastern Seaboard through the weekend. By early next week, conditions should gradually improve as the system moves offshore, though some lingering precipitation may affect coastal areas.
Temperature Anomalies:
-Days 1-3: Near normal to slightly below normal temperatures across most of the Northeast, with slightly cooler conditions in Florida. Warming trend begins by day 3.
-Days 4-6: Temperatures trending cooler across the Northeast with below normal readings, particularly in New York and New England. Near normal elsewhere in the region.
-Days 7-10: Generally near normal temperatures returning to the entire Eastern region, with slight above normal readings developing in the Ohio Valley and Mid-Atlantic by the end of the period.
CENTRAL: High pressure will dominate the Central US through Friday, bringing generally dry conditions. By Saturday, a frontal boundary will begin to push through the region, with a low pressure system developing over Missouri. This will bring rain to portions of the Central Plains and Midwest. As the system evolves, thunderstorms may develop across parts of Oklahoma and Texas by Monday. The cold front will continue to push southeastward through the period, bringing precipitation to much of the region. No significant severe weather is currently indicated, though some thunderstorm activity is possible in the southern portions of the region early next week.
Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the entire Central region, with anomalies of 6-12 degrees above normal, particularly in the Northern Plains and Upper Midwest. Peak warmth on Saturday.
-Days 4-6: Continued above normal temperatures, though moderating somewhat. Warmest conditions shifting southward into Oklahoma, Arkansas, and Texas with 6-10 degree anomalies.
-Days 7-10: Gradual moderation of temperatures, but still remaining above normal across most of the region, particularly in the South Central states. Near normal conditions returning to the Northern Plains by day 10.
WEST: An active weather pattern will affect the Western US throughout the period. Multiple low pressure systems will impact the Pacific Coast, bringing significant precipitation to the region. Heavy rain is expected across California, particularly on Friday and Saturday, with potential for flash flooding in some areas. The heaviest precipitation will focus on central and southern California, where rainfall rates could exceed flood thresholds. Mountain snow will develop across the Cascades, Sierra Nevada, and northern Rockies. By Sunday and into early next week, precipitation will spread eastward into the Great Basin and Intermountain West. Another system approaches the Pacific Northwest by Tuesday, bringing additional rain and mountain snow to the region.
Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the West, particularly in the interior portions with anomalies of 4-8 degrees above normal. Near normal along the immediate Pacific Coast.
-Days 4-6: Cooling trend begins, with temperatures returning closer to normal across much of the region. Some below normal readings developing in parts of California and the Southwest.
-Days 7-10: Generally near normal temperatures prevailing across most of the West, with some slightly below normal readings in parts of California and Nevada. Slight warming trend in the interior West by day 10.
TROPICAL: No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
